Physics with far detectors at futu ⋯タイプ: Oral presentation using Zoom

Physics with far detectors at future lepton colliders
2021 年 10 月 28 日木曜日 15:30 (30 分)
At the Large Hadron Collider (LHC), several far detectors such as FASER and MATHUSLA havebeen proposed to target the long-lived particles (LLPs) featured with displaced vertices. Naturally
one question arises as to the feasibility of installing similar far detectors at future lepton colliders like the CEPC and FCC-ee. Because of the different kinematics of final state particles and thefreedom to locate both the experiment hall and the detectors, the future lepton collider with anadditional far detector may play a unique role in searching for LLPs. In this study, we consider
various locations and designs of far detectors at future e− e+ colliders and investigate their potentials for discovering LLPs in the physics scenarios including exotic Higgs decays, heavy neutral
leptons, and the lightest neutralinos. Our analyses show that the kinematical distinctions between
the lepton and hadron colliders render the optimal positions of far detectors lying at the direction
perpendicular to the collider beams at future e− e+ colliders, in contrast to the LHC where a boost
in the forward direction can be exploited. We also find that when searching for LLPs, such new experiments with far detectors at future lepton colliders may extend and complement the sensitivity
reaches of the experiments at the future lepton colliders with usual near detectors, and the present
and future experiments at the LHC. In particular, we find that, for the theory models consideredinthis study, a MATHUSLA-sized far detector would give a modest improvement compared to thecase with a near detector only at future lepton colliders.

The search for leptophilic WIMP at ILC
2021 年 10 月 27 日水曜日 14:20 (20 分)
We consider the renormalizable leptophilic WIMP models with the scalar mediators which have
lepton numbers. We perform a comprehensive analysis for such a WIMP scenario for two distinct
cases with SU(2) doublet or singlet mediators considering all the relevant theoretical, cosmologicaland experimental constraints at present. We show that mono-photon search at ILC experiment canplay a significant role to probe the yet unexplored parameter region. Furthermore, we discuss thecapability of explaining the muon g-2 anomaly by combined model scenario including both the
doublet and singlet mediators.

In this work, we study the production of color-neutral and singly-charged heavy leptons at the
proposed International Linear Collider. We use the optimal observable technique to determine
the statistical accuracy to which the coupling of such fermions to the Z gauge boson (vector,
axial or chiral) can be measured. We also consider a UV-complete model that contains these particles as well as a dark matter candidate, and consider some observable effects involving both; thecorrespondence to chargino production in supersymmetric models with heavy sleptons is briefly
discussed.

Development of hydrofluoric acid- ⋯タイプ: Oral presentation using Zoom

Development of hydrofluoric acid-free EP treatmentof Nb cavities at KEK
2021 年 10 月 28 日木曜日 14:00 (30 分)
The ILC project will require ˜8000 9-cell Nb cavities. In the fabrication process of Nb cavities, electrolytic polishing (EP) treatment is essential for the high SRF performance of the cavities. However,
the electrolyte is a mixture of hydrofluoric acid and concentrated sulfuric acid, and its toxicity to
the human body and environment is extremely high. HF-EP facilities become more complex toensure chemical safety and prevent environmental leaks, and the workers are required to haveadvanced chemical knowledge and work experience. For that reason, EP-related expenses in the
ILC project account for a very large proportion.
The HF-EP treatment of the Nb cavity in KEK was started in 2008, and a large amount of EP effluent
containing fluoride has been treated. Meanwhile, we have been developing the bipolar EP (BP-EP)
method in collaboration with Nomura Plating and Marui Plating. However, the BP-EP method is
not energy efficient and requires a very high power programmed power supply to process a 9-cell
Nb cavity. Also, since a relatively high concentration of sulfuric acid solution is used as the electrolyte, the cost reduction is limited.
Recently, the application of the plasma-EP (PEP) method, in which metal surfaces are polished byhigh-voltage plasma discharge, to Nb surfaces has been promising. The PEP method is chemicallysafe because it uses an inorganic salt aqueous solution as the electrolyte, and the polishing rate is
tens of times faster than that of HF-EP. Also, the PEP method is suitable for local polishing of Nb
cavities, which enables the polishing process of Ti-jacketed Nb cavities. That is expected to greatly
reduce the cost of the ILC project. Now, KEK starts to establish the PEP method for Nb cavities,
and some experimental concepts will be introduced in this presentation.

Recent direct detection experiments put the strong constraint on WIMPs at the electroweak scale,and people have started focusing on light DM scenario. For the light thermal scalar DM, it is usuallyconstrained by the CMB observation because it annihilate at s-wave. Despite of CMB constraint,
We have revealed that some parameter regions are still surviving for the model with singlet scalar
mediator, which are resonant annihilation region and forbidden annihilation region. We analyze
these regions quantitatively, considering theoretical and experimental constraints.

Experiments at a future + − collider will be able to search for new particles with masses below
the nominal centre-of-mass energy by analyzing collisions with initial-state radiation (radiative
return). We show that machine learning methods based on semisupervised and weakly supervised
learning can achieve model-independent sensitivity to the production of new particles in radiative
return events. In addition to a first application of these methods in + − collisions, our study isthe first to combine weak supervision with high-dimensional information by deploying a deepsets neural network architecture. We have also investigated some of the experimental aspects ofanomaly detection in radiative return events and discuss these in the context of future detector
design.

Jim Brau (U. Oregon), Martin Breidenbach (SLAC), Lorenzo Rota (SLAC), et al.
The SiD Collaboration has had a long interest in the potential for improved granularity in the
tracker and ECal; a study of MAPS in the SiD ECal was described in the ILC TDR. Work is progressing on the MAPS application in an upgraded SiD design, both for the ECal and tracking. A
prototyping design effort is underway for a common SiD tracker/ECal design based on stitchedreticules to achieve 10 x 10 cm2 sensors with 25 x 100 micron2 pixels. Application of large area
MAPS in these systems would eliminate delicate and expensive bump-bonding. The small pixels
significantly improve shower separation. Recent simulation studies confirm previous results, indicating electromagnetic energy resolution based on digital hit cluster counting provides better
performance than the SiD TDR analog design based on 13 mm2 pixels. Furthermore, two shower
separation is excellent down to the millimeter scale. Geant4 simulation results will be presented
demonstrating these expectations.

Two-loop corrections to the Higgs ⋯タイプ: Oral presentation using Zoom

Two-loop corrections to the Higgs trilinear couplingin classically scale-invariant BSM models
2021 年 10 月 28 日木曜日 19:00 (20 分)
The Higgs trilinear coupling provides can serve as a unique probe to investigate the structure of
the Higgs sector and the nature of the electroweak phase transition, and to search for indirect signsof New Physics. Meanwhile, classical scale invariance (CSI) is an attractive idea for BSM modelbuilding, which can explain the apparent alignment of the Higgs sector and potentially relate to
the hierarchy problem. A particularly interesting feature of models with CSI is that the Higgs
trilinear coupling is, at one loop, universally predicted to deviate by 67% from the (tree-level) SM
prediction.
In this talk, I will discuss how this result is modified at two loops. I will present results fromthe first explicit computation of two-loop corrections to the Higgs trilinear coupling in classicallyscale-invariant BSM models. Taking as example a CSI variant of a Two-Higgs-Doublet Model, I
will show that the inclusion of two-loop effects allows distinguishing different scenarios with CSI,
although the requirement of correctly reproducing the known 125-GeV mass of the Higgs boson
severely restricts the allowed values of the Higgs trilinear coupling.

Chronopixel Silicon CMOS Sensor ⋯タイプ: Oral presentation using Zoom

Chronopixel Silicon CMOS Sensor Development for
the ILCA monolithic silicon CMOS pixel detector with time-stamping capability (Chronopixel)
has been developed based on design goals of the International Linear Collider(ILC). Each hit is accompanied by a time tag with sufficient precision toassign it to a particular ILC bunch crossing - thus the name Chronopixel. This
reduces the occupancy to negligible levels, even in the innermost vertex
detector layer, yielding a robust vertex detector which operates at backgroundlevels significantly in excess of those currently foreseen for the ILC.
The Chronopixel can record and store time stamps for two hits in each pixel
while using standard CMOS processing for manufacturing. Following two earlier
prototype fabrication runs and tests, a third prototype design was developed
to resolve earlier issues, including a high capacitance problem. This problem
was traced to the TSMC 90 nm technology design rules, which led to an
unacceptably large value of the sensor diode capacitance. Six different layouts
for the sensor diode were tested in the third prototype, and tests demonstrated
that the high capacitance problem was solved. The third prototype has also been
exposed to HL-LHC radiation levels; results of these tests are also presented.
Simulation of the signal formation from charge particle crossing detector with
one particular sensor design also was done and results will be shown.

Neutron Production at the ILC

Neutron Production at the ILC
2021 年 10 月 27 日水曜日 16:42 (24 分)
Neutrons are widely used for material sciences, imaging, fundamental physics and so on due toits unique properties. Recently, spallation neutron sources using megawatt class accelerators arecoming up as next-generation neutron sources instead of research reactors. A spallation neutron
source irradiates proton beam with energy of a few GeV into a neutron spallation target made ofa heavy elemental material. Neutrons are produced via spallation reaction with kinetic energy ofseveral MeV, and were cooled down in a moderator to 1˜100 meV, which are commonly used ascold or thermal neutrons. Produced neutrons have pulse structure. This nature is applied for TOF
analysis, which is essentially outperform reactor neutron sources. However, the spallation neutron source needs huge neutron shield about 10-m diameter. It makes the neutron facilities large
and costly, and also prevent to approach by the neutron source. Since both neutron target andaccelerator are closing to the engendering limit, higher power neutron sources are getting moredifficult. Thus, more effective way to produce neutrons is expected.
Photo-neutron production reaction using pulsed gamma beam can be a candidate of a new neutron source which works without moderator to realize short timing and compactness[1]. The
International Linear Collider (ILC) is a proposed electron-positron collider whose collision energy
is 200-500 GeV [2]. It is planning to build a positron source using pulsed gamma rays generated
by 150-250 GeV electron beam through a helical undulator. In this talk, I will report an evaluationof its performance of the photo-neutron source using the gamma rays and possible applications.

If nature is supersymmetric and not fine-tuned, higgsinos may well be within the reach of the
ILC. In the NMSSM extended with right-handed neutrinos the right-handed sneutrino is a viable
thermal dark matter candidate. We discuss how a light higgsino-type chargino could decay to asneutrino and a charged lepton with a branching ratio O(10ˆ-5). Such a decay will be unobservable
at the LHC, but in an electron-positron collider the decay can be observed. The measurement of
the branching ratio would allow us to estimate the size of the neutrino Yukawa couplings.

Blockchain is a technology used to create distributed ledgers and to achieve consensus regarding
data between distributed entities. Although the technology has been used to perform extremelycomputationally calculations involving cryptocurrency, its use in the scientific world has been
limited.
In this paper we identify several possible use cases by which blockchain could be applied to scientific computing. These use cases include creating parallel computing systems from heterogeneous
service providers, allowing for researchers to publish systems that allow service based architectures, integrating exotic technologies such as quantum computing, and archiving data and calculation chains to allow for reproduciblity of results.
We further detail the limitations and deficiencies of current blockchain systems for use to aid
scientific supercomputing and propose characteristics of a blockchain systems which would be
neccessary to support scientific supercomputing. Specifically we propose a blockchain protocolthat would allow scientists to run existing scientific code in a distributed fashion.

Probing new physics with a LUXE-type experimentat the ILC
2021 年 10 月 27 日水曜日 19:30 (30 分)
The proposed LUXE experiment (LASER Und XFEL Experiment) at DESY, Hamburg, using the16.5 GeV electron beam from the European XFEL, aims to probe QED in the non-perturbative
regime created in collisions between high-intensity laser pulses and high-energy electron or photon beams. This setup also provides a unique opportunity to probe physics beyond the standard
model by leveraging the large photon flux generated at LUXE, probing axion-like-particles (ALPs)
at a reach comparable to FASER2 and NA62. In this contribution we will explore the sensitivity of
a LUXE-type experiment using the ILC electron beam instead of the EU.XFEL one.

Probing non-perturbative QED in electron-LASER
and photon-LASER collisions at the ILC
The LUXE experiment (LASER Und XFEL Experiment) is a new experiment in planning at DESY
Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions
between a high-intensity optical laser and 16.5 GeV electrons from the XFEL electron beam, as
well as collisions between the optical LASER and high-energy secondary photons. The physics
objective of LUXE are processes of Quantum Electrodynamics (QED) at the strong-field frontier,where the electromagnetic field of the laser is above the Schwinger limit. In this regime, QED
is non-perturbative. This manifests itself in the creation of physical electron-positron pairs fromthe QED vacuum, similar to Hawking radiation from black holes. LUXE intends to measure thepositron production rate in an unprecedented LASER intensity regime. In this contribution an
overview of the LUXE experimental setup and its challenges will be given, followed by a discussionof the expected physics reach of a similar experiment using the ILC electron beam instead of the
EU.XFEL one.

Fermion pair production at e−e+ linear collider
experiments in GUT inspired gauge-Higgs
unification
2021 年 10 月 27 日水曜日 15:30 (20 分)
In gauge-Higgs unification (GHU), the 4D Higgs boson appears as a part of the fifth dimensional
component of 5D gauge field. Recently, an SO(11) GUT inspired SO(5) × U (1) × SU (3) GHU
model has been proposed. In the GHU, Kaluza-Klein (KK) excited states of neutral vector bosons,photon, Z boson and ZR boson, appear as neutral massive vector bosons Z ′ s. The Z ′ bosons
in the GHU couple to quarks and leptons with large parity violation, which leads to distinctive
polarization dependence in, e.g., cross sections and forward-backward asymmetries in e− e+ →µ− µ+ , q q̄ processes.
In the talk, we discuss fermion pair production in e− e+ linear collider experiments with polarized
e− and e+ beams in the GUT inspired GHU. Deviations from the SM are shown in the early stageof ILC 250 GeV experiments. The deviations can be tested for the KK mass scale up to about 15
TeV.
This talk is mainly based on Phys.Rev.D102(2020)015029 collaborated with S. Funatsu, H. Hatanaka,
Y. Hosotani, and Y. Orikasa.

Particle identification with time-of-flight
2021 年 10 月 28 日木曜日 16:42 (24 分)
A particle identification is an essential tool for precision measurements at the ILC. Recent development of the fast-timing Si sensors with a time resolution below 100 ps gives a possibility for the
π ± , K ± , p separation using time-of-flight measurements. In our study we use ILD as an example
to test different potential placements of the fast-timing Si sensors for instance in the SET and inner
ECal layers simulating possible time resolution scenarios. In this talk we present latest results on
the performance of the time-of-flight particle identification.

2021 年 10 月 28 日木曜日 13:30 (30 分)
A linear e+e- collider with energy recovery (ERLC) is considered. To avoid parasitic collisions
inside the linac a twin LC is proposed. The acceleration gradient is 20 GeV/m, Q=3.10ˆ10. For
2E=250 GeV, the luminosity is about 5.10ˆ35 when working with a duty cycle 1/3 and total power
P=130 MW. With the power about 250 MW, it can work in continuous mode and produce L=10ˆ36.
This is a “green”collider, two orders of magnitude more efficient than the ILC.

We consider a gamma-gamma collider with W<12 GeV based on 17 GeV linac of the EU XFEL. Highenergy photons will be obtained by Compton scattering of 0.5 μm laser photons on the existing
17.5 GeV electron beams. Such a collider would be an excellent place for the development andapplication of modern technologies needed for the PLC: powerful lasers, optical cavities and lowemittance electron sources. The physics program would include spectroscopy of C=+ resonances
in various JˆP states. Variable circular and linear polarizations will help in the determination ofquantum numbers. It is shown that two-photon resonances in the 10 GeV region can be wellobserved in the presence of a large multi-hadron background.

Diversified use of ILC: A possibility of hadronphotoproduction experiments at a beam dump
2021 年 10 月 27 日水曜日 15:30 (24 分)
The ILC provides an extremely high energy electron beam with an excellent beam divergence.
Thus, a linearly polarized photon beam of about 75 GeV can be produced by coherent bremsstrahlung
using a thin diamond radiator. Thanks to the electron beam polarization, it is also possible to generate a circularly polarized photon beam. Such a very high energy photon beam would be useful to
produce exotic hadrons with charm or bottom quarks and to investigate their natures through polarization observables. This talk will present a possibility of hadron photoproduction experiments
at a beam dump as a diversified use of ILC.

Future electron-positron colliders will allow us to test Standard Model physics, especially for theelectroweak sector, to an unprecedented level of precision, which could reveal signs for new
physics that were previously inaccessible. This requires the theory side to put effort into two
aspects. First, we need to link observables predicted by models to the experimental process in amodel-independent and theoretically well-defined way. Secondly, we need to carry out the relevant radiative corrections up to the new precision frontier given by the future colliders for eachexperimentally and theoretically well-defined precision observable. In this talk, we will addresssome work done, also provide an outlook on future work concerning these two aspects.

such high intensity lasers and the ultrahigh energy electron and positron beams of the ILC will
result in laser photons with energies comparable the electron rest mass colliding with electronsor positrons at rest in the center-of-mass frame. Having such collisions after the interaction point
will provide a unique opportunity to study high field science and applications. We will present
simulation results of the interaction using the CAIN code and discuss the fundamental physics

Impact of overlay events on the charged IDM scalarreconstruction at CLIC
2021 年 10 月 27 日水曜日 19:20 (20 分)
The Inert Doublet Model (IDM) is one of the simplest SM extensions and introduces four new
scalar particles: H± , A and H; the lightest, H, is stable and hence it is a natural dark matter (DM)candidate. A set of benchmark points is considered, which are consistent with current theoreticaland experimental constraints and promise detectable signals at future colliders. Discovery reachfor the IDM charged scalar pair-production is considered for the semi-leptonic final state at the twohigh-energy CLIC stages. Five selected benchmarks were analysed with full detector simulationand the study was extended to more scenarios using Delphes fast simulation.
In the several benchmark scenarios, the small mass splitting between scalars H± and A makes the
final state reconstruction vulnerable to beam-induced γγ → hadrons overlay events. It is, however,not possible to apply the same background mitigation procedure in Delphes as implemented in thefull CLIC detector simulation and reconstruction algorithms. Therefore, an approximate method oftaking it into account has been developed and the results obtained this way show good agreementwith the full simulation.

Searching for Charged via e+e− → H +H − → b̄cbc̄ atLinear colliders
2021 年 10 月 27 日水曜日 10:00 (20 分)
We present a search for the charged Higgs boson via e+ e− →H + H − →bcbc at the 500 GeV ILC.
In a general two Higgs doublet model without Z2 symmetry, extra Yukawa couplings such as ρtc
and ρtt can drive baryogenesis, but searches at the HL-LHC may still come away empty-handed.
In this report, we take m( H + ) = mH = mA = 200 GeV with ρtc = ρtt = 0.1, and no h(125)-H
mixing. We study the four jet final state with two b-tagged, which would clearly be overwhelmed
by QCD background at LHC, but with electroweak production of H + H − at ILC, the signal is
discoverable. We find that ILC can capture this signature with significance at 20σ or better withintegrated luminosity of 1 ab−1 . We also show that the mass of Hˆ+ can be recovered by requiring
the two b and light jet pairs be approximately equal in mass, without assuming the mass. Thus,
ILC can probe low mass Higgs bosons in multijet final states to compliment HL-LHC in the future.

Optimising top-quark threshold scan using genetic
algorithm
2021 年 10 月 27 日水曜日 16:42 (20 分)
One of the important goals at the future e+ e− colliders is to measure the top-quark mass andwidth in a scan of the pair production threshold. However, the shape of the pair-production crosssection at the threshold depends also on other model parameters, as the top Yukawa coupling,
and the measurement is a subject to many systematic uncertainties. Presented in this work is thestudy of the top-quark mass determination from the threshold scan. The most general approachis used with all relevant model parameters and selected systematic uncertainties included in thefit procedure. Based on the procedure developed for CLIC, results assuming the ILC luminosity
spectra are presented. Expected constraints from other measurements are also taken into account.
It is demonstrated that the top-quark mass can be extracted with precision of the order of 30 to
40 MeV, including considered systematic uncertainties, already for 100 fb−1of data collected at
the threshold. Additional improvement is possible, if the running scenario is optimised. With
the optimisation procedure based on the genetic algorithm the statistical uncertainty of the massmeasurement can be reduced by about 25%. Influence of the collider luminosity spectra on the
expected precision of the measurement is also studied.

defines the language physicists can use to express their ideas and also how different software components communicate with each other. The Key4hep project aims to develop a common software
stack for all future collider projects. As the common EDM for all these projects, EDM4hep is oneof the corner stones of the Key4hep project. EDM4hep is implemented via the podio EDM toolkit
and a prototype version, based on LCIO, has been designed. We will present some of the technicaldetails of the implementation of EDM4hep and podio. Based on that we will discuss some of thesimilarities and differences between EDM4hep and LCIO. We will highlight some experiences withthe usage of EDM4hep in the Key4hep framework and give an outline for future plans.

Forward Backward Asymmetry studies with heavy
quarks (b/c) at ILC250
2021 年 10 月 27 日水曜日 15:54 (20 分)
The process ee->qq (with q from u to top) plays a central role in the physics programs of highenergy electron-positron colliders operating from the O(100GeV) to O(1TeV) center of mass energies. Furthermore, polarised beams as available at the International Linear Collider (ILC) are an
essential input for the complete measurement of the helicity amplitudes that govern the production cross section. Quarks, specially the heaviers, are likely messengers to new physics and at thesame time they are ideal benchmark processes for detector optimisation. We will present detailed
studies for the bottom and charm quarks production at 250GeV using ILD full simulation.
These measurements require superb primary and secondary vertex reconstruction, a high tracking
efficiency to correctly measure the vertex charge and excellent hadron identification capabilities.
We will show how that we can reach 0.1% - 0.5% level of experimental precision, including a comprehensive study of the systematic uncertainties. We will also outline the capabilities of indirect
discovery of new physics as Randall-Sundrum models with warped extra dimensions.

The THDMa and possible e+e- signatures
2021 年 10 月 27 日水曜日 19:00 (20 分)
The THDMa is a new physics model that extends the scalar sector of the Standard Model by anadditional doublet as well as a pseudoscalar singlet and allows for mixing between all possible
scalar states. In the gauge eigenbasis, the additional pseudoscalar serves as a portal to the dark
sector, with a priori any dark matter spin states. The option where dark matter is fermionic iscurrently one of the standard benchmarks for the experimental collaborations, and several searches
at the LHC constrain the corresponding parameter space. However, most current studies constrain
regions in parameter space by setting all but 2 of the 12 free parameters to fixed values.
I will discuss a generic scan on this model, allowing all parameters to float. All current theoreticaland experimental constraints are applied. I identify regions in the parameter space which are stillallowed after these have been applied and which might be interesting for an investigation at afuture e+e- collider.

2021 年 10 月 28 日木曜日 15:30 (20 分)
We report on studies of the e+ e− → HZ process with the subsequent decay of the Higgs boson H → ZZ ⋆ , where the ZZ ⋆ combination is reconstructed in the final states with two jets
and two leptons. The analysis is performed using Monte Carlo data samples obtained with detailed ILD detector simulation assuming the integrated luminosity 2 ab−1 , the beam polarizations√
calP e− e+ = (−0.8, +0.3), and the center-of-mass energy s = 250 GeV. The analysis is also repeated for the case of two 0.9 ab−1 data samples with polarizations calP e− e+ = (∓0.8, ±0.3).
Contributions of the potential background processes are taken into account based on the available
MC event samples. The e+ e− → HZ process measurement allows to obtain the width of the
Higgs boson in a model-independent approach.

Dark Matter and Collider Searches at ILC in S3-Symmetric 2HDM with Vector Like Leptons
2021 年 10 月 27 日水曜日 15:30 (20 分)
We study the S3 -symmetric two Higgs doublet model by adding two generations of vector like
leptons (VLL) which are odd under a discrete Z2 -symmetry. The lightest neutral component of
the VLL acts as a dark matter (DM) whereas the full VLL set belongs to a dark sector with nomixings allowed with the standard model fermions. We analyse the model in light of dark matterand collider searches. We show that the DM is compatible with the current relic density data aswell
as satisfying all direct and indirect dark matter search constraints. We choose some representative
points in the model parameter space allowed by all aforementioned dark matter constraints andpropose a few collider signatures, namely di-lepton, four-lepton and mono-lepton+2jet along withtransverse missing energy that can be easily tested at the International Linear Collider (ILC), in
contrast to the LHC machine due to cleaner backgrounds.

A new (Very) Front-End Board for the ILD SiW-ECAL
2021 年 10 月 27 日水曜日 16:20 (20 分)
The Silicon-Tungsten ECAL (SiW-ECAL) of ILD will require about 10,000 detector slabs of 1.4 to 1,8m in length. For the ease of building and testing, the slabs are made of stitched detector elementsof 18×18 cm², composed of a Front-End Board (FEB), hosting the readout ASICs for 1024 channels,
on which the Silicon sensors are glued.
Various types of detector elements have been successfully tested individually; the first attempt tochain them into a long slab in 2018, while globally positive, hinted at some improvements.
As its predecessor, the new FEB will handle 16 SKIROC 2A chips, amplifying, shaping, pipelining
and digitizing the data generated by collisions at the International Linear Collider ILC, taking
advantage of its pulsed operations to reduce the power dissipation.
This presentation describes the FEB design, adapted for long slabs composed of up to 10 FEB, toperform power supply distribution (now locally pulsed), local high voltage distribution (to reduce
intervention and handling). Also, will be show preliminary results on power supply, slow control
and leackage current measurements on 1 to 5 FEB chained.

The traditional purpose of the ECAL of the ILD experiment is to measure neutrals(especially photons but also the interacting neutral hadrons) while tracking thecharged particles for particle flow algorithms.
A highly granular Silicon-Tungsten ECAL (SiW-ECAL) is particularly suited for these tasks.
The SiW-ECAL faces many technical challenges: the main ones have been solved,
some remains to be tackled, while new ones, such as a precise timing, still need to be fully evaluated.
It is proposed here to make a review of the art on all these issues.

Radiative Neutrino Mass with GeV Scale Majorana
Dark Matter in Scotogenic Model
2021 年 10 月 28 日木曜日 20:20 (20 分)
The experimental observations from the colliders established the standard model (SM), the mostsuccessful phenomenological framework to explain the non-gravitational interactions of fundamental particles at high energy. Non-zero neutrino mass and dark matter cast a shadow
over its success. This necessitates the extension of the SM. The most straightforward and elegant
extension of the SM to explain these two phenomena is the Scotogenic model, where the SM particle
spectrum extends with three isospin singlet right-handed neutrinos and one doublet scalar while
all of these being odd under Z2 symmetry. In this work, we have considered the lightest righthanded neutrino as the dark matter candidate and freeze-out mechanism for producing the observed
dark matter relic density. The charged lepton flavor violation decay processes constrain the upperside of Yukawa coupling while the observed relic density limits the lower side. We have performed
a unique parameterization to attain the highest possible Yukawa coupling while satisfying LFV andDM constraints. The reduced number of free parameters and large Yukawa coupling makes themodel predictability at lepton colliders very high. Collider phenomenology for possible signatures
performed at lepton colliders and the required luminosities estimated for detection. The exclusion
bounds on the inert charged scalars were recast at the 13 TeV LHC.

In this talk, I discuss the phenomenology of a minimal model for GeV-scale Majorana dark matter(DM) coupled to the standard model lepton sector via a charged scalar singlet. The theoreticalframework extends the Standard Model by two SU (2)L singlets: one charged Higgs boson and asinglet right-handed fermion. The latter plays the role of the DM candidate. We show that there isan anti-correlation between the spin-independent DM-Nucleus scattering cross-section (σSI ) andthe DM relic density for parameters values allowed by various theoretical and experimental constraints. Moreover, we find that even when DM couplings are of order unity, σSI is below thecurrent experimental bound but above the neutrino floor. Furthermore, we show that the considered model can be probed at High Energy lepton colliders using e.g. the mono-Higgs production
and same-sign charged Higgs pair production.

Precision measurements of the properties of the discovered Higgs boson are one of the main programs at current and future collider experiments. At the international linear collider with thecenter-of-mass energy 250 GeV, e+e- → hZ is the dominant Higgs production process, and thecross section would be measured with a few percent accuracies. In this talk, we present the crosssection of the e+e- → hZ process at full next-to-leading order in various extended Higgs models.
In addition, by using the H-COUP program, we analyze the deviations in the cross section times
decay branching ratios of the discovered Higgs boson. We discuss the discrimination of extended
Higgs models at the future colliders in detail. This talk is based on arXiv:2109.02884.

This requires a relatively lightelectroweak sector of the MSSM, which in turn can give rise to positive contributions of the Wboson mass, MW .

CP asymmetries of B to X_{s,d} g ⋯タイプ: Oral presentation using Zoom

CP asymmetries of B to X_{s,d} gamma in models
with three Higgs doublets
2021 年 10 月 28 日木曜日 19:20 (20 分)
We study the prediction of the direct CP asymmetry in the inclusive decays of B to X_s gamma
and B to X_{s+d} gamma in the context of a three-Higgs-doublet model(3HDM). The 3HDM is thesimplest multi-doublet model such that the charged Higgs mixing includes a physical CP phase.
We show that the CP asymmetries can be as significant as the current experimental limit. In
particular, the asymmetry for B to X_{s+d} gamma, which is effectively zero in the Standard Model,
is interesting. A measurement of 2.5% or more for this observable with the full BELLE II data would
give 5σ evidence for physics beyond the SM. We display parameter space in the 3HDM for whichsuch a clear signal is possible.
The presentation is essentially based on the paper, A. G. Akeroyd, S. Moretti, T. Shindou and M.
Song, Phys. Rev. D 103 (2021) no.1, 015035.

2021 年 10 月 27 日水曜日 15:55 (20 分)
A highly granular silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is the reference design of the ECAL for International Large Detector (ILD) concept, one of the two detector concepts
for the detector(s) at the future International Linear Collider. Prototypes for this type of detector
are developed within the CALICE Collaboration. The technological prototype addresses technicalchallenges such as integrated front-end electronics or compact layer and readout design. During Autumn/Winter 2019/20 a stack of up to 22 layers with a dimension of ˜18×18×25cmˆ3 wascompiled. A beam test at DESY is planned for November 2021.
We will present the status and latest developments of the hardware aspects of the prototype andthe status of the implementation in simulation.

Precise determination for properties of the Higgs sector is one of the most important issues toclarify physics beyond the SM.
For this purpose, we have developed the numerical tool HCOUP, and its
version 1 (1-loop calculation for the Higgs boson couplings)
and version 2(1-loop calculation for the Higgs decay rates) have been published.
We give a brief review of
H-COUP and show how it works for precise calculations.
We also discuss future prospects ofthe H-COUP project.

Prospects of charged Higgs in two Higgs doublet
model at the LHC
2021 年 10 月 28 日木曜日 20:00 (20 分)
Extension of the Higgs sector is ubiquitous in physics beyond the Standard Model (BSM), andthe two Higgs Doublet Model (2HDM) is one of the simplest extensions containing two scalar
doublets instead of one for electroweak symmetry breaking. In the first half of the talk, I will
discuss the exclusion limits on the charged Higgs parameter space, mH ± − tan β, using the CMS√
results on the upper limits on σH ± BR(H ± → τ ± ν) and σH ± BR(H + → tb̄) for s = 13 TeV at
an integrated luminosity of 35.9 fb−1 . The exclusions obtained at 13 TeV will be compared to theearlier 8 TeV results. The CMS collaboration also studied the exotic bosonic decay H ± → W ± A
and A → µ+ µ− for the first time and put upper limits on the BR(t → H + b) for light charged
Higgs. These constraints lead to exclusion of parameter space which are not excluded by the τ νchannel. In the second half, I will talk about the prospect of looking for a fermiophobic charged
Higgs via the same sign trilepton signal at the LHC. Such a fermiophobic scenario appears in TypeI 2HDM
where the fermionic couplings of the charged Higgs are inversely proportional to tan β. For afermiophobic case, the electroweak production of charged Higgs is dominant for large tan β andthe subsequent bosonic decay of the charged and neutral Higgs will give rise to the same sign
trilepton signal which can be an excellent complementary search to explore the large tan β regions.

Leptoquarks and Zeros of Amplit ⋯タイプ: Oral presentation using Zoom

Leptoquarks and Zeros of Amplitude atElectron-Photon Collider
2021 年 10 月 28 日木曜日 17:10 (20 分)
Though leptoquarks have gained much attention in recent time due to their ability to explain
various flavour anomalies, their existence is not confirmed yet experimentally [1]. But, we findthat zeros of single photon tree level amplitude [2,3] have the potential to provide information
about leptoquarks (if any) at electron-photon collider [4]. It is a well known fact that the tree-level
single photon amplitudes for various electroweak processes vanish at certain regions of phasespace depending on the electric charges and four-momenta of the external particles [3]. On theother hand, using the technique of laser-backscattering [5], one electron-positron collider can betransformed to an electron-photon collision machine. A small number of SM backgrounds would
keep the signal very clean in this collider. We have used a PYTHIA based simulation for productionof leptoquark associated with a quark at electron-photon collider to obtain the results which arevery encouraging.

Generative Models for Hadron Shower Simulation
2021 年 10 月 28 日木曜日 15:54 (24 分)
Generative machine learning models offer a promising way to simulate events. Given the alreadyhigh computational cost of simulation and the expected increase in data in the high-precision eraof the LHC and at future colliders, such fast surrogate simulators are urgently needed.
This contribution presents initial progress towards accurately simulating of hadronic showers in ahighly granular scintillator calorimeter for future colliders. We used two generative models in thisstudy: a Wasserstein-GAN (WGAN) and Bounded Information Bottleneck Autoencoder (BIB-AE).
Then we compare the achieved simulation quality before and after interfacing with the state-of-theart pattern recognition algorithm used by ILD, the so-called PandoraPFA. This brings generativemodels one step closer to practical applications.

Stau Searches at the ILC

Stau Searches at the ILC
2021 年 10 月 28 日木曜日 19:20 (20 分)“The direct pair-production of the tau-lepton superpartner, stau, is oneof the most interesting channels to search for SUSY. First of all the stau iswith high probability the lightest of the scalar leptons. Secondly thesignature of stau pair production signal events is one of the most difficult
ones, yielding to the ‘worst’ and so most global scenario for the searches.
The current model-independent stau limits comes from analysis performed at
LEP but they suffer from the low energy of this facility. The LHC exclusion
reach extends to higher masses for large mass differences, but under strongmodel assumptions.
The ILC, a future electron-positron collider with energy up to 1 TeV, is apromising scenario for SUSY searches. The capability of the ILC for determining
exclusion/discovery limits for the stau in a model-independent way is shown inthis contribution, together with an overview of the current state-of-the-art.
A detailed study of the ‘worst’ scenario for stau exclusion/discovery taking
into account the effect of the stau mixing on stau production cross-sectionand efficiency is presented. For selected benchmarks, the prospect for measuring
masses and polarised cross-sections will be shown. The studies were done using
the sgv fast simulation adapted to the ILD detector concept at the ILC.”

CMOS pixels sensors R&D for the ILC vertex detector
2021 年 10 月 28 日木曜日 16:10 (20 分)
A Monolithic CMOS Pixel Sensors (CPS), MIMOSIS, is currently being developed in the TJ-180nm
technology by IPHC/IKF/GSI to equip the Micro-Vertex Detector (MVD) of the CBM heavy ion
experiment at FAIR/GSI and within the CREMLIN+ program. Thanks to its targeted performances(5 microns spatial resolution/5 micro-second time resolution) MIMOSIS will reach a milestone for
the ILC vertex detector requirements. The first full size prototype (MIMOSIS-1) has been fabricatedin 2020, containing both AC and DC pixels, and reached a step forward concerning the data flowthat CPS can handle in this technology with a pitch smaller than 30 microns. In 2021, Mimosis-1 has
been tested extensively in lab and beam at DESY II test beam facility and CERN-SPS with different
sensitive layers. Charged particle detection performances (Efficiency and spatial resolution) will
be presented in different configurations. Preliminary results with irradiated chips will also be
discussed. Sensors adapted to the ILC requirements are expected to be directly derivable from thischip, with spatial resolution of about 4 microns, a time resolution of about 1-2 micro-seconds andan instantaneous data flow of about few GB/s while keeping the Power consumption in a range
compatible with air flow cooling.
A second part of the talk will adress the development of the 65 nm process. This technology is expected to offer new perspectives and improvements in terms of granularity, time resolution, power
consumption and possibly stitching to cover large area detectors. Several laboratories coordinatedby CERN (ALICE ITS3 WP2 and CERN EP WP 1.2) realized a first joined submission in 2020. IPHC
has contributed to this effort concentrating on different test structures and several functionnal
small-size prototypes (CE_65) with analog output, offering the possibility to be tested in beam forcharged particle detection. Preliminary results of the first tests of CE_65 will be presented.

Charged Higgs boson decays with NLO corrections
in two Higgs doublet models
2021 年 10 月 28 日木曜日 20:40 (20 分)
While the Higgs boson with the mass of 125GeV was discovered at the LHC experiment, the shapeof the Higgs sector remains unknown.
Hence, one can consider various possibilities of extended Higgs models.
The property of the discovered Higgs boson will be precisely measured in future collider experiments such as ILC.
This requires theoretical predictions for the discovered Higgs boson should be precisely evaluated.
In addition, precise calculations of additional Higgs bosons are inevitable in case that they are discovered.
In this work, we comprehensively studied radiative corrections to charged Higgs boson decays,
focusing on two Higgs doublet models (THDMs) with softly broken Z_2 symmetry.
In this talk, we explain why the radiative corrections to charged Higgs boson decays can be important, and describe which type of corrections can be significant.
We also discuss how four types of THDMs can be separated by decay patterns of the charged Higgs
boson,
assuming the situation that the Higgs boson coupling with the Z boson is precisely measured at
ILC.

The complementarity of searches for new physics has become increasingly important in recent
years, and therefore global analyses of BSM models, including constraints from many sources, arenecessary for a full understanding on their validity. In this talk I will describe a global analysis
of a model with three right-handed neutrinos using the GAMBIT tool, with constraints from cosmological sources, such as BBN, direct searches for heavy neutrinos at colliders and beam dump
experiments, and a collection of indirect constraints, such as neutrinoless double beta decay andlepton flavour violation. I will also argue that searches for heavy neutral leptons, such as righthanded neutrinos, should be an important part of the research program of future experiments suchas those at the ILC, as the most interesting parameter region falls within its energy reach and theresults will make significant impact on our understanding of neutrino masses.

Measurement of particle energy with homogeneous
calorimeter
2021 年 10 月 27 日水曜日 13:24 (24 分)
We have fond a relation between the energy deposit and track length in a homogeneous calorimeter
situation with GEANT4 at high energy. The relation holds for different materials of the calorimeter from 1 to 100GeV energy range. The energy deposit and track length have a linear relation
with positive intercept for both of pions and electrons. The tilt of the straight lines for pion andelectron are the same independent of the injection energy. The intercept is proportional to theinjection energy linearly, therefore we are able to measure the particle energy as a calorimeter.
The resolution of such calorimeter is represented by two quantities and about 20%/sqrt(E).
We discuss the relation and how to realize the calorimeter in this talk.

We studied phenomenological implications of numerous Family Non-Universal U(1)′ sub-models
in the minimal U(1)′ extended Supersysmmetric Model (UMSSM) possessing an extra down quark
type exotic field. In doing this, we started with anomaly cancellation criteria to generate a numberof solutions in which the extra U(1)’ charges of the particles are treated as free parameters. We
imposed existing bounds coming from colliders and astrophysical observations on the assumed
sub-models and observed that current limits dictate certain orientations.
Related with potential impact of non universal charges on the Z’ decays we made predictions forthe existing and future experiments. We also probe the signatures of the exotic quark and thenon-universality at the future Linear Colliders.

Studying exotic gauge bosons using ILC beam-dump
2021 年 10 月 28 日木曜日 11:12 (24 分)
We discuss the prospect of detecting new gauge bosons (like the dark photon and leptophilic gaugebosons) using the ILC beam dump, assuming that muon shield, veto counter, and particle detector
are installed behind the beam dump. Because the e± beams are dumped after each collision at
the ILC, a large number of electrons and positrons are available for the beam dump experiment.
If a new gauge boson exists, it can be produced in the beam dump, go through the shield, anddecay inside the decay volume to be detected by the particle detector. We show that, with thedesign luminosity, parameter regions that have not been excluded by other experiments so far
can be accessed by the ILC beam dump experiment. We also discuss the possibility to distinguishdifferent models of new gauge bosons by identifying the decay products of the new gauge boson.

The CLIC Tracker Detector (CLICTD) is a monolithic CMOS silicon pixel sensor that targets therequirements for the tracking detector of the Compact Linear Collider (CLIC). CLICTD is characterised by a small collection diode that allows for a low sensor capacitance and consequently
a high signal-to-noise ratio. The front-end design features an innovative sub-pixel segmentation
scheme to reduce the digital footprint while maintaining a small sub-pixel pitch of 30 um x 37.5
um. In this contribution, recent test-beam results for CLICTD samples featuring different starting
materials and sensor thicknesses are presented.

Mo-99 production at cERL in KEK
2021 年 10 月 27 日水曜日 17:06 (24 分)
Medical RI production is a very promising application of superconducting (SC) linear accelerator. SC LINAC can easily generate large averaged current beam of higher energy than those fromindustrial electron sources for the electron beam (EB) processing where RI production must be
avoided. ILC type long pulsed SC LINAC has great cost efficiency due to low duty factor where
RF heat load can almost be negligible. For the target design, pulsed operation requires treatment
for thermal impulse that is negligible in the continuous wave (CW) accelerators. If we have large
space, newly developing Nb3Sn based low gradient SC accelerator can be available with conductive cooling system without liquid helium. Nuclear fission reactor can generate medical RI withvery high specific radioactivity from low enriched uranium, but large radioactive nuclear waste
generated at the same time. Hadron accelerators seems to have subjects of short of beam power
for yield and generation of unwanted RI that become contamination. Comparing with advantages
and disadvantages, SC LINAC of mA or sub-mA class averaged current with dozens MeV energy
seems to be very suitable for medical RI production. In this presentation, we show the advantage
of ILC type SC LINAC for medical RI production and results of the test production of Mo-99 at
cERL (CW SC LINAC) in KEK.

We obtain the upper bound on the new physics scale as a functionof the Higgs coupling deviation factor by considering the perturbative
unitarity of 2 → 2 scattering amplitudes among the longitudinallypolarized electroweak gauge bosons and the Higgs bosons.
We estimate the unitarity bound in a new effective field theory
which parameterizes the sizable non-decoupling effects fromthe new physics in the Higgs self-couplings. Our effective field theory iscontracted based on the experimental fact that the Higgs couplings
to electroweak bosons/fermions are consistent with those predictedin the SM within O(10%) error.

2021 年 10 月 27 日水曜日 17:06 (20 分)
We present a new measurement of the bottom quark mass based on the determination of Higgs
decay rates to bottom quarks. The current measurements by ATLAS and CMS yield a value for thebottom quark at the scale of the Higgs boson mass mb(mH) = 2.6 GeV, with an uncertainty of lessthan 15%. The theory uncertainty has been investigated in detail and is found to be a fraction of
the current experimental uncertainty. The prospects for this measurement at the ILC are excellent,with the statistical uncertainty reaching several tens of MeV. Confronting this determination athigh scale with the PDG world average for mb(mb) based on low-energy measurement and themeasurement of mb(mZ) at LEP and using SLC data, we find strong evidence for the scale evolutionof the bottom quark, as predicted by the renormalization group equations in QCD.

Study of photon-associated Higgs production at the
ILC
2021 年 10 月 28 日木曜日 16:30 (20 分)
In the Standard Model（SM）, hγZ coupling is a loop induced coupling, therefore it might receive
relatively large correction from Beyond Standard Model（BSM）physics. It is very challenging tomeasure at the HL-LHC, where only 3σ significance is expected for branching ratio of h → γZ.
On the other hand, hγZ coupling is potentially very sensitive to new physics, for example some
new heavy particles contributing to the loop, therefore it is interesting to know how well thiscoupling can be measured at the International Linear Collider (ILC). More over, it is found hγZ
coupling plays an important role in a framework of effective field theory, for example in e+ e− →Zh process it is necessary to know the contribution from s-channel with photon. It turns outthat the anomalous hγZ , hγZ , hZZ and hW W couplings come from a few common set of
dimension-6 operators, and hγZ coupling measurement can provide very useful constraints on
those operators.
In this talk, we will report the study of hγZcoupling using production channel e+ e− → γh, withfinal results based on the full simulation of ILD. Results will be given for an integrated luminosityof 900 f b−1 for polarization at ECM = 250GeV .

process is back ground free process. In final state, RHN pair production shows the same sign leptons.
We generated this process, investigate event properties, develop reconstruction and selection strategies and evaluate the sensitivity at ILC. In our study, we use the Delphes simulation of a parametrized

Analyzing the Higgs potential in gauge-Higgs
unification with a flat extra dimension
2021 年 10 月 27 日水曜日 11:00 (20 分)
We investigate the structure of the Higgs potential in gauge-Higgs unification with a flat extra
dimension. As a viable gauge-Higgs unification model, we take the one where the Standard
Model Higgs doublet is embedded into a higher-dimensional SU(3)w gauge multiplet and relax
five-dimensional Lorentz symmetry. In this model, the deviation in the triple Higgs boson coupling from its SM prediction is shown to be smaller than 10% for compactification scales larger
than the experimental bound around 5 TeV. We also generalize about the analysis of the Higgs
potential to other gauge-Higgs unification models with a flat extra dimension. It is shown that inthis class of models the shape of the Higgs potential around the vacuum quickly approaches thatof the minimal Higgs potential with one Higgs doublet as the compactification scale increases. An
observable deviation in the triple Higgs boson coupling at the ILC will compel us to significantly
extend such gauge-Higgs unification models. This is based on collaboration with Mr. Shin Suzuki
published in Phys. Lett. B822, 136637 (2021).

2021 年 10 月 27 日水曜日 13:00 (20 分)
The neutrinos have tiny mass which is not predicted in the Standard Model. Therefore the extension of the SM is unavoidable. A plethora of scenarios have been proposed to explain the originof the tiny neutrino mass which include tree level, quantum level and gauge extensions of theSM. In this talk we will discuss about the simple tree level neutrino mass models. Such models
can include SM singlet heavy neutral fermionic, SU (2) triplet fermionic and SU (2) triplet scalarparticles to describe the origin of the tiny neutrino mass and flavor mixing reproducing the neutrino oscillation data. There is another simple but interesting thought is to extend the SM using ageneral U (1) gauge group which demands the addition of three generations of the right handed
neutrinos to get the anomaly free framework. After the U (1) symmetry breaking, the Majorana
mass term of the RHNs are generated which can explain the origin of the tiny neutrino mass. In
this talk we will discuss a variety of production channels of such beyond the SM particles at the−+colliders which are responsible for the generation of the tiny neutrino mass.

production
2021 年 10 月 27 日水曜日 15:50 (20 分)
The minimal (1) extension of the Standard Model (SM) is a well-motivated new physics scenario,
where the anomaly cancellation requirement dictates the new neutral gauge boson (′ ) couplings
with the SM fermions in terms of two scalar charges ( and Φ ). In this paper, we investigate the
SM charged fermion pair production mechanism for different values of these scalar charges in the(1) scenario at future electron-positron colliders, i.e. +− → . Apart from the standard photon
and boson exchange for this process, this model features a -channel (or both and -channel
for = − ) ′ -boson exchange, which interferes with the SM processes. Considering the dileptonand dijet signatures from the heavy resonance we estimate the bounds on the U (1) coupling (′ )and the ′ mass (′ ). Considering the LEP-II results and prospective International Linear Collider(ILC) bounds on the effective scale for the four fermion interaction we estimate the reach on ′ /′ fordifferent center of mass energies. We study the angular distributions, forward-backward (AFB ),left-right (ALR ) and left-right forward-backward (ALR, FB ) asymmetries of the final states which
can show substantial deviations from the SM results, even for a multi-TeV �. This provides a powerful complementary way to probe the heavy ′ parameter space beyond the direct reach of the Large
Hadron Collider (LHC), as well as an effective way to determine the (1) charges.

This upper bound is obtained even though the h(125) coupling is standard model-like. Second, weshow that both precise measurements of the triple Higgs boson coupling at ILC and gravitational
wave observations through LISA, DECIGO, and BBO are important to distinguish whether themass of the additional Higgs bosons is relatively light or heavy.

We study the measurement of Higgs boson self-couplings through 2→3 vector boson scattering (VBS) processes in the framework of Standard Model effective field theory (SMEFT) at bothproton and lepton colliders. The SMEFT contribution to the amplitude of the 2→3 VBS processes, taking WLWL→WLWLh and WLWL→hhh as examples, exhibits enhancement with theenergy A(BSM)/A(SM)∼Eˆ2/Λˆ2, which indicates the sensitivity of these processes to the related
dimension-six operators in SMEFT. Simulation and analysis of the full processes with backgrounds
at future muon colliders are performed to constraint on c6 and cΦ1. The results are optimistic andcomparable to di-Higgs production with 2->2 VBS.

Possibility of multi-step electroweak phasetransition in the two Higgs doublet models
2021 年 10 月 28 日木曜日 17:10 (20 分)
In this talk, we discuss whether a multi-step electroweak phase transition (EWPT) occurs in two
Higgs doublet models (2HDMs). We examine parameter regions in CP-conserving 2HDMs andfind certain areas where the multi-step EWPTs occur. In addition, we compute the Higgs trilinear
coupling in the parameter region where the multi-step EWPTs occur, which has the tendency to
be large in a certain region comparing that for the 1-step EWPTs. Especially, when the first stepof the 2-step EWPT is strongly first order, we find the deviation of the coupling from that in the
SM is more than about 50%, which can be detected in the ILC operating at 500 GeV.

Higgs boson pair production at NNLO in the large
top quark mass approximation
2021 年 10 月 28 日木曜日 13:40 (20 分)
We consider the next-to-next-to-leading order (NNLO) total cross section of Higgs boson pair
production at LHC in the large top quark mass approximation.
At hadron collider, the partonic cross section consists of various initial states such as gluon-gluon,
gluon-quark, quark-quark, and we calculated all of them analytically within this approximation.
We found that, in some cases, the corrections of 1/mtˆ4 and 1/mtˆ6 which we compute here enhance
the NNLO cross section significantly.

Top electro-weak couplings, from ⋯タイプ: Oral presentation using Zoom

Top electro-weak couplings, from the LHC to the ILC
2021 年 10 月 29 日金曜日 13:23 (23 分)
As the heaviest particle of the model, with a mass close to the electroweak scale, the top quark is aninteresting candidate to look for hints of new physics. The electroweak couplings of the top quarks
are specially relevant in many extensions of the Standard Model. Indeed, as the top quark was notproduced in the previous generation of electron-positron colliders most of its electro-weak couplings can only be constrained with the data from the Large Hadron Collider. In order to analyse
if there is still room for new physics in the electro-weak couplings of the top quark, we perform a
global fit to these couplings. Following the Standard Model Effective Field Theory formalism wehave constrained the Wilson coefficients of the dimension-six operators that affect the top quark
electro-weak couplings. In this work we consider, for the first time, the QCD corrections at NLO
for most of the processes included. Furthermore, we have included recently measured processes,
such as tZq and tγq, and the first differential measurements in tt̄Z and tt̄γ production. A special
effort is made to understand the uncertainties due to the truncation of the EFT expansion anddue to the poorly known correlations among measurements. The results of the fit to LHC run 2
data are compared to prospects for electron-positron colliders operating above the top quark pair
production threshold, considering in particular the ILC runs at 500 GeV and 1 TeV. As the main
result, we present bounds on the relevant operator coefficients based on current data and on future
prospects.

Search for new light particles usi ⋯タイプ: Oral presentation using Zoom

Search for new light particles using MeV photon
beam at the ILC
2021 年 10 月 28 日木曜日 16:30 (30 分)
As a postron source at the ILC, it is discussed to use pair creation processes by a O(MeV) photon
beam, which is generated from the high-energy electron beam. The current design expects thatthe photon flux would be as intense as 1017 photons / s, being the strongest MeV photon source
available on the ground.
We propose to use this photon beam for the search for new light particles. As a benchmark model,
we discuss the dark photon and the QCD axion. The use of the energetic photon beam opens
a new window for relatively heavy mass regions, i.e. ≤ O(100) eV. We have found that our
proposal can constrain not only new parameter regions as a ground experiment but also somephysical parameter region of the QCD axion.

Tau reconstruction in e+e− → τ +τ − at the ILC250
2021 年 10 月 27 日水曜日 19:48 (24 分)
The International Linear Collider (ILC) is a next-generation electron-positron linear collider proposed to search for new physics beyond the Standard Model.
In the ILC, the International Large Detector (ILD) has been proposed as a detector for the precise
measurement of final state particles. Collision of electron and positron generates tau lepton pairin ILC experiment. This process can be used to search for new interactions, also making use of ourability to measure the tau polarisation. Correct reconstruction of the tau decay mode is important
for the tau polarisation measurement.
In this study, we explicitly extract neutrino momentum to calculate optimal polarimeters whichis the cosine of the angle the polarimeter vector makes to the tau flight direction including the
momenta of neutrino, charged and neutral pions.
The aim of this study is reconstruction of tau spin in order to measure polarisation to investigate
new physics and to estimate how well we can reconstruct these polarimeter distributions using
fully simulated, reconstructed, and selected events.

CMOS Upgrade to the Belle II Ve ⋯タイプ: Oral presentation using Zoom

CMOS Upgrade to the Belle II Vertex Detector
2021 年 10 月 28 日木曜日 15:30 (20 分)
The success of the Belle II experiment at KEK (Japan) relies on the very high instantaneous luminosity, close to 6x10ˆ35 cm-2 s-1, expected from the SuperKEKB collider. The beam conditions toreach such luminosity levels generate a large rate of background particles in the inner detection
layers of Belle II. The hit rate in the innermost vertex detector layer will exceed 100 MHz/cm2
translating into radiation levels of 100 Mrad TID and fluences reaching 5x1014 neq cm-2. This
beam-induced background creates stringent constraints on the vertex detector, in addition to therequirements coming from the physics performance needed.
Belle II has started to define a vertex detector upgrade program to make it more robust and performant even in the presence of high backgrounds facilitating the SuperKEKB running at highluminosity, coupled to an accelerator consolidation in the timeframe of 2026-2027.
In this context, the Belle II collaboration is considering the possibility to install an upgraded alllayer monolithic pixel vertex detector on the time scale around 2026 and R&D activities on fully
depleted CMOS sensors have started. Such an upgrade should provide a sufficient safety factor
with respect to the background rate expected at the nominal luminosity and possibly enhance
performances with improved vertex resolution and higher tracking efficiency at low momentum
range.
New CMOS monolithic technologies for pixel sensors offer a combination of granularity, speed,
low material budget and radiation tolerance. In particular, latest developments on the TJ-Monopix2
family make this development to match Belle II requirements and will be the baseline to exploit
the design of a fully pixelated 5 layer vertex detector, called VTX.
This talk will review the context of the proposed VXD upgrade with monolithic technologies in
Belle II, providing details of the technological proposal, system integration and discussing performance expectations from simulations.

Influence of dark matter spin on detection
possibility at future e+e− colliders
2021 年 10 月 28 日木曜日 20:40 (20 分)
It is commonly believed that Dark Matter (DM) should exist in the form of new, Beyond-theStandard-Model stable particles.
Despite continued efforts, such particles have not yet been detected, which means that interactions
between DM and SM must be very weak. Dark particles, even if they are already produced atexisting colliders, evade detection due to tiny signal-to-background ratio.
However, future e+ e− colliders (e.g. ILC), provide large luminosity and collision energy as well asvery clean collision environment (which means low background). They may potentially lead to abreakthrough in the search for dark particles.
In this talk, I will estimate the maximal possible cross section for DM production, calculated withinsimple (but QFT-consistent) models of Higgs-mediated dark matter of different spins. The estimations will be based on current theoretical constraints and experimental limits on DM-SM interaction strength. For each considered value of DM spin, I will present allowed parameter spaceand compare the expected signal to the background, determining whether dark particles could be
discovered at high confidence level.

The scenario of electroweak baryogenesis in the CP violating extended Higgs model has beenstrongly limited by current EDM experiments, hence it is difficult to generate the observed baryon
density in our universe. Recently, in the CP violating Two Higgs doublet model, which has the SM
like coupling of the 125GeV Higgs and the yukawa sector avoiding FCNC, it was shown that the
EDM constraints can be avoided by the destructive interference between two independent additional CP phases. Using this idea, we have calculated the baryon density in this model and foundthe benchmarks which explain the observed baryon density satisfying the current experimental
data. We will show the results and discuss the predictions in the ILC and other future experiments.

timing measurements for single ionising particles. It features a small collection-electrode design
on a 30 micron deep epitaxial layer and contains 32 mini matrices of 68 hexagonal pixels each, 4transmitting an analog output signal and 64 transmitting binary hit information, with pixel pitches
ranging from 8.66 to 20 micron. Various process- and design variations are explored, aiming at accelerating the charge collection and making it uniform over the pixel area. Signal treatment of theanalog waveforms as well as reconstruction of Time-of-Arrival and Time-over-Threshold information is carried out off-chip.
This contribution introduces the design of the sensor and readout system, and presents first performance results achieved in measurements with particle beams.

Software tools are foundational for the development of future collider experiments. Detector optimization and physics performance studies crucially depend on the availability of performant andreliable software libraries. The Key4hep project aims at providing infrastructure, interfaces, anda common stack of easy-to-use software tools for future, or even present, High Energy Physics
projects. Key4hep is to a large extent based on software tools that are already very actively usedin the community - like ROOT, Geant4 and DD4hep or those that are currently under active development like EDM4hep or ACTS. The Key4hep project is supported by, among others, the HEP
Software Foundation, CERN, DESY and the AIDAinnova project and has active developers fromall large future collider projects: CEPC, CLIC, FCC, and ILC. In this talk we present an overview
of the Key4hep project and describe the adaptation processes of the different future experiments,
in particular the consolidation of different fast and full simulation workflows in the Gaudi framework, thereby showing that Key4hep is a viable long term solution as baseline software for highenergy experiments that will facilitate the scientific exchange and make similar studies easier andmore efficient.

Angular Conditioning of Generative Models for Fast
Calorimeter Shower Simulation
2021 年 10 月 28 日木曜日 15:30 (24 分)
Detector simulation is a key cornerstone of modern high energy physics. Traditional simulation
tools are reliant upon Monte Carlo methods, which consume significant computational resources
and are projected to be a major bottleneck at the high luminosity stage of the LHC and for futurecolliders. Calorimeter shower simulation has been a focus of fast simulation efforts, as it is particularly intensive from a computational stand point due to a large number of particle interactions
with the detector material.
Deep generative models hold promise as a potential solution, offering drastic reductions in compute times. Recent work in our group in the context of the ILD concept has demonstrated the suitability of various generative models for accurately reproducing showers displaying key physics
properties in a highly granular calorimeter. While this initial work focused on the specific caseof a particle incident perpendicular to the calorimeter face, a practical simulator must incorporate
arbitrary angles of incidence and simulate them correctly. This talk will address ongoing efforts
to add conditioning on the incident angle of the particle.

New approach to validation of simulations withhighly granular calorimeters using machine learningtechnique2021 年 10 月 28 日木曜日 16:18 (24 分)
An estimation of detector performance for future particle physics experiments relies both on prototypes tests and on detector simulation quality. Though the most used packages like Geant4
demonstrate quite good agreement, at percent level, for many observables, they are not perfectyet in the description of topological aspects of hadronic shower development, which are important for Particle Flow reconstruction. Highly granular calorimeters provide a wide spectrum ofcalorimetric observables and help to go deeper in our understanding of the source of discrepancies between data and simulations. In this work, we show the relationships between observables,
which are available in the highly granular CALICE analogue hadron calorimeter, and propertiesof secondaries generated by Geant4 during hadronic shower propagation. In the new approach
proposed, several calorimetric observables are used as inputs to a neural network and the output/target variable is one of the properties of secondary particles in a shower. The regression
model is trained using a supervised learning. The achieved performance of the model and perspectives of its implementation for validation of hadronic shower simulations at secondaries level are
discussed.

Probing Dark Sectors With Invisible Vector Meson
Decays2021 年 10 月 28 日木曜日 11:36 (24 分)
Fixed target experiments such as NA64 and LDMX use missing energy-momentum to detect the
production of dark matter and other long-lived states. The most studied production mechanism
is dark Bremsstrahlung through a vector mediator. In this work, we explore a complementarysource of missing energy-momentum signals: Bremsstrahlung photons can convert to hard vector
mesons in exclusive photoproduction processes, which then decay to dark matter or other invisible particles. We find that existing NA64 data can improve the leading constraints on invisible
light vector meson decays, while a future run of LDMX could improve them by up to 5 orders ofmagnitude. For the examples of a dark photon and a U (1)B gauge boson mediator, accounting
for meson decays substantially enhances these experiments’ sensitivity, especially to thermal relicdark matter of mass mχ > 0.1 GeV. We also comment on their implications for ILC beam-dump
experiments.

A model for tiny neutrino masses, ⋯タイプ: Oral presentation using Zoom

A model for tiny neutrino masses, dark matter, andbaryon asymmetry and its phenomenology at the ILC
2021 年 10 月 27 日水曜日 13:40 (20 分)
The origin of tiny neutrino masses, dark matter, and baryon asymmetry of the universe is still amystery, and there is no doubt that there is new physics beyond the Standard Model. In a previous
work, a new physics model at TeV-scale where all of them can be explained has been proposed,
however the authors neglected CPV phases, and on the baryon asymmetry, they only showed
the possibility of the strongly 1st order phase transition for the electroweak baryogenesis. We
have extended this model to include CPV phases and evaluated neutrino masses, dark matter,and the baryon number asymmetry generated by the electroweak baryogenesis. In this talk, I
will introduce this model and discuss the phenomenology at current and near future experiments
including the ILC.

Digital Hadron Calorimetry
タイプ: Oral presentation using Zoom

Digital Hadron Calorimetry
2021 年 10 月 27 日水曜日 19:25 (20 分)
Particle Flow Algorithms (PFAs) attempt to measure each particle in a hadronic jet individually,using the component or detector subsystem providing the best energy/momentum resolution.
Calorimeters that can fully exploit the power of PFAs emphasize spatial granularity over single
particle energy resolution. In this context, the CALICE collaboration developed the Digital Hadron
Calorimeter (DHCAL).
The DHCAL uses Resistive Plate Chambers as active media and is read out with 1 x 1 cm2 pads
and digital (1-bit) resolution. The DHCAL was tested with steel and tungsten absorber structures,
as well as with no absorber structure, at the Fermilab and CERN test beam facilities over several
years. The test program yields a unique dataset of electromagnetic and hadronic interactions with
unprecedented spatial resolution. In addition to conventional calorimetry, the DHCAL offers detailed measurements of event shapes, rigorous tests of simulation models and various analytical
tools to improve calorimetric performance.
Here we report on the results from the analysis of DHCAL data and comparisons with the Monte
Carlo simulations across various test campaigns.

We study the scenario of the two Higgs doublet model, where the Higgs potential respects thetwisted custodial symmetry at a high energy scale. In this scenario, experimental data for the Higgs
boson couplings and those for the electroweak precision observables can be explained even whenthe masses of the extra Higgs bosons are near the electroweak scale. We also discuss the predictions
on the mass spectrum of the additional Higgs bosons and also those on the coupling constants ofthe standard-model-like Higgs boson, which make it possible to test this scenario at the current
and future collider experiments. This talk is based on JHEP 02 (2021) 046 [arXiv:2009.04330].

Impact of light dark matter on Higgs physics
2021 年 10 月 27 日水曜日 10:20 (20 分)
We explore a novel possibility that dark matter has a light mass below 1 GeV in a lepton portal
dark matter model. There are Yukawa couplings involving dark matter, left-handed leptons andan extra scalar doublet in the model. In the light mass region, dark matter is thermally produced
via its annihilation into neutrinos. In order to obtain the correct relic abundance, a neutral scalar
is required to be light while charged scalars need to be heavier than the electroweak scale. Such amass spectrum is realized by adjusting quartic couplings in the scalar potential or introducing an
extra singlet scalar. We discuss constraints of the light dark matter from Higgs physics, as well as
dark matter searches.

Status of the MUonE experiment2021 年 10 月 27 日水曜日 20:12 (24 分)
The MUonE experiment aims at a competitive determination of the leading hadronic contribution
to the muon anomalous magnetic moment, completely independent from the other existing results.
It could have a crucial role to clarify the comparison of the aµ measurement with the Standard
Model, given the recent Fermilab result, and the tension between the accepted theory prediction
and a new Lattice QCD calculation.
The novel method requires a precise measurement of the hadronic component of the runningelectromagnetic coupling, which can be extracted from the shape of the differential cross sectionof µe elastic scattering, obtained by the 160 GeV CERN muon beam on fixed target.
The project status is presented, in view of the test run on a reduced detector, which is starting inFall 2021 and will be completed in 2022.

Higgs couplings to charged leptons forms an important measurement to understand not only theStandard Model but also physics beyond Standard Models including, multihiggs models , supersymmetric models etc. In the present work, We focus on the complementarity between the direct
and indirect measurements in fixing the charged Lepton Yukawa couplings including flavour violating couplings. We show that the present limits from LHC are already competing with theindirect flavour violating measurements in some cases. We then comment on future possible measurements of these couplings including those from FCC-ee, ILC etc. We then extend our analysis
to two Higgs doublet models of type III.

Neutral and Doubly-Charged Scalars at Future
Lepton Colliders
Many new physics scenarios beyond the Standard Model (BSM) often necessitate the existenceof new neutral and/or charged scalar fields, which might couple to the SM charged leptons andthus give some BSM signals while evading all existing constraints. We show that future lepton
colliders provide a clean environment to probe these BSM including some interesting lepton flavor
violating (LFV) signals. We study the distributions of the final state leptons to distinguish the BSM
contributions from neutral and doubly-charged scalars each other, as well as from the irreducible
SM background at future lepton colliders, such as ILC and CLIC.

Highly granular electromagnetic calorimeter based on scintillator strip with SiPM readout (ScECAL) is under development in the framework of the CALICE collaboration for future electronpositron colliders such as ILC and CEPC. The detection layers with scintillator strips (45 mm ×
5 mm × 2 mm each) coupled to SiPMs are stacked alternately in an orthogonal orientation. This
technique achieves an effective transverse segmentation of 5 × 5 mm2 , and allows to significantly
reduce the number of readout channels. After the validation of the concept with the physics prototype, the fully integrated technological prototype with 32 layers has been constructed to demonstrate the performance of Sc-ECAL with more realistic technical implementation. The assemblyof the prototype has been completed, and the calibrations for the detection layers are in progressusing the cosmic-ray and LED. The performance of the prototype is evaluated using the cosmicray shower, and test beam which is planned at the IHEP. The status and prospects of the R&D of
Sc-ECAL will be reported.

Scattering amplitudes in generalized Higgs effective
field theory
2021 年 10 月 28 日木曜日 11:40 (20 分)
The HEFT is the most general effective field theory with non-linearly realized electroweak symmetry, but it cannot treat the production or decay processes of new particles. In the previous work,
we extend the HEFT so that it includes the arbitrary number of neutral and charged scalar fields.
In some of the BSM models such as composite Higgs models, however, the SM fermion partners
are predicted in addition to the new scalar matter fields at low energy region, and in order to treat
these additional fermions in a consistent manner, we have to extend the HEFT so that it includes
not only new scalars but also these new fermion fields.
In the recent work, we formulate the generalized HEFT including new fermion fields as well as new
scalar fields. We calculate scattering amplitudes in a basis-independent manner and find that theirhigh energy behaviors are controlled by the geometrical quantity in the extended target space,such as Riemann curvature tensors.

Searches for extra Higgs bosons are quite important for a direct test of models with extended Higgs
sectors. On the other hand, recent LHC data indicates that properties of the discovered Higgs boson are consistent with the SM Higgs boson within the error.
This favors a nearly alignment scenario in models with extended Higgs sectors, where the discovered Higgs boson couplings are almost the same as those of the SM Higgs boson at tree level.
We show that in such an alignment scenario the decay branching ratio of a heavy Higgs boson
into the SM-like Higgs bosons can significantly be modified at one-loop level
as compared with the tree level prediction. In particular, we discuss two Higgs doublet models as
an important example.

The International Large Detector (ILD) is a detector concept for the International Linear Collider(ILC). ILD is a general purpose detector designed to fully reconstruct almost all events. A particularemphasis has been put on excellent jet energy resolution (JER), by optimizing the detector for
efficient particle flow reconstruction. Excellent understanding of the absolute jet energy scale (JES)
is needed to fully profit from excellent JER. We have developed a data-driven method to extract theabsolute JES using the e+e- -> γZ process. This method makes use of measured jet masses and jet
and photon directions to extract jet energies without reference to the directly measured energies.
Comparing the extracted and directly measured jet energies will allow a very precise control of the
JES to 10 MeV or better for ˜100 GeV jets. We present the result of a full-simulation demonstrationof this new method, including an evaluation of the achievable JES accuracy and its dependence on
jet energy, direction and flavor.

2021 年 10 月 27 日水曜日 21:30 (30 分)
In the international linear collider (ILC), a high-intense electron beam passes through a helicalundulator to produce a multi-MeV circularly polarized photon beam before it is directed to the interaction point (IP). The photon beam hits a thin rotating target to produce electron positron pairs.
A maximum active undulator length of 231 m is foreseen to be appropriate for the ILC 250 GeV
center-of-mass energy. Since the photon produced by the undulator is created with an opening
angle, some of these photons will strikes the superconducting undulator wall. Therefore, photon
masks must be placed along the undulator line to keep the power deposited into the undulator
walls at an acceptable level (1 W/m). This talk will discuss the power deposited into the undulator
walls. Masks inserted in the undualor line are discussed assuming ideal and realistic undulator
fields; as material copper or tungsten are considered in detail.

Models with scalar doublets and charged scalar singlets have the interesting property that they
have couplings between one Z boson and two charged scalars of different masses. This property
is often ignored in phenomenological analysis, as it is absent from models with only extra scalar
doublets. We explore this issue in detail, considering h → Zγ, B → Xs γ, and the decay of a heavycharged scalar into a lighter one and a Z boson. We propose that the latter be actively searched forat the future collider experiments, using the scalar sector of the Zee-type models as a prototype
and proposing benchmark points which obey all current experimental data.

The Analog Hadron Calorimeter (AHCAL) concept developed by the CALICE collaboration is ahighly granular sampling calorimeter with 3*3 cmˆ2 plastic scintillator tiles individually read out
by silicon photomultipliers (SiPMs) as active material. A large technological prototype has been
built and tested in particles beams at DESY and CERN in 2018, and analyses of this data set are
well progressed.
Since then, the hardware developments and tests are focused on two areas:- an alternative readout ASIC (KLauS) which supports operation in power-pulsing mode as well as
continuous readout,- an alternative scintillator geometry (Megatiles) where the segmentation of larger scintillator
plates into small tiles is achieved by grooves filled with reflective material.
In addition, dedicated studies have been performed with individual tiles in order to understand theeffects dominating the time resolution.
The talk will present an overview of the analyses as well as the hardware developments.

A tapered pulsed solenoid as optical matching device
for the undulator-based ILC positron source
2021 年 10 月 27 日水曜日 22:30 (30 分)
Future high energy colliders like the ILC require high intensity positron beams to achieve theirtargeted high luminosities. The intensity of positron beams is partially defined by the amountof positrons that can be provided by the positron source, which arises from the amount of originally produced positrons and the fraction that can be captured and transported, the so-called yield.
In current positron source designs devices like the flux concentrator and the quarter wave transformer are used to match the positrons which are extracted from the positron target into the firstaccelerating structure. As these conventional devices exhibit a limited positron yield and posehigh challenges on the target design due to the large forces and eddy currents that they induceon it, alternative matching devices are under investigation. In this contribution we present conceptual studies of a tapered, pulsed solenoid as matching device for the ILC positron source. The
principal setup, simulated positron yield and heat load on the target, as well as approaches on how
to improve them are discussed.

Center-of-mass energy determin ⋯タイプ: Oral presentation using Zoom

Center-of-mass energy determination using dimuon
events at ILC
2021 年 10 月 27 日水曜日 20:36 (24 分)
Precision measurements of masses from both center-of-mass energy scans and using beam energy
and momentum constraints rely on knowledge of the absolute center-of-mass energy scale and√√the luminosity spectrum, dL/d s. A key method is the sp technique that uses the tracker muon√
momenta measurements in e+ e− → µ+ µ− (γ) events to determine both s and the related luminosity spectrum. The talk will describe recent studies aimed at evaluating this method using√
fully reconstructed ILC events at s = 250 GeV including detector effects, crossing-angle, beamenergy-spread, beamstrahlung, overlay, ISR, FSR, backgrounds, and investigations of vertex fitting.
The same event sample is also used to evaluate sensitivity to the Z mass and width.

Di-Higgs production (γγ → hh) in Composite Models

In Standard Model (SM) Higgs Boson pair production initiated by photons (γγ → hh) loop generated process and thereby is very sensitive to any new couplings and particles that may come inloops. Composite Higgs Models (CHMs) provide an alternate mechanism to address the hierarchy
problem of SM where Higgs could be a bound state of a strongly interacting sector instead of being
an elementary field. These set of models apart from modifying the SM Higgs couplings could also
introduce new effective couplings that can have substantial impact on the loop processes. In thiswork we have studied the impact of Composite Higgs models in γγ → hh (Di-Higgs) production
process.

High-voltage CMOS detectors are based on innovative structure where a pixel consists of a single

Since they are implemented in a commercial CMOS process, the production of large area sensors is
inexpensive. The latest pixel detector designs designed for tracking detectors at electron-electron

Quest for Dark Matter at International Linear
Collider2021 年 10 月 27 日水曜日 16:10 (20 分)
Future accelerators like ILC or CLIC are with immense possibilities to improve our understandingof nature’s fundamental building blocks and to discover new particles, e.g., WIMPs along withother physics phenomena. In scenarios where dark matter does not or feebly couple with quarks,
we can consider the dominant couplings of them with charged leptons. We consider the pair
production of fermion dark matter (freeze-out) at 1TeV ILC using a class of higher-dimensional
leptophilic operators. Depending upon the visible particles to identify the events, we probe monophoton and mono-Z (with Z decays leptonically and hadronically) channels. We also employ thebeam polarisation scheme of ILC and present the 3σ sensitivity at 1000fb−1 in terms of the newphysics (NP) scale Λ, for the three channels. I will discuss here how these operators perform in
the quest for dark matter signature and how constrained the parameter space stand considering
different experimental bounds.

Update on the Development of the Active Plasma
Lens as an Alternative Optical Matching Device
2021 年 10 月 27 日水曜日 23:00 (30 分)
The optical matching device (OMD) is responsible for matching the positron beam, produced in
the target, according to the damping ring acceptance. This makes the OMD a crucial component
for the number of positrons available in the collision experiments. The active plasma lens (APL)
is a current-carrying plasma with the potential of being an innovative alternative for traditional
OMD concepts as, for instance, the quarter wave transformer (QWT). This is due to its azimuthal
magnetic field, which leads notably to focusing in both planes and due to minimal eddy currents
inside the rotating target. Furthermore the plasma is transparent for incoming beams. Simulations
with the ASTRA code suggest an increase in number of captured positrons by up to 40% relative
to the ILC’s current QWT design. Recently a German funding grant has been approved for further
theoretical and experimental research, including setting-up a prototype experiment.

Timing reconstruction with deep learning

Pico-sec timing reconstruction is one of the hot topics of the detector development. We are working on timing reconstruction in calorimeters with utilizing hits as many as possible to be averaged.
It needs precise tracking in the calorimeters to precisely calculate flight length inside the calorimeters. Since the tracks in the calorimeters are much more complicated than those in trackers, deeplearning techniques such as graph neural network should be powerful. We will present the statusof the current development. Our other efforts on application of deep learning for event reconstruction will be briefly discussed as well.

Towards a Pixel TPC

Towards a Pixel TPC
2021 年 10 月 28 日木曜日 19:40 (20 分)
We have developed a gaseous pixel detector based on four Timepix3 chips that can serve as abuilding block for a large detector plane. To provide the required gas amplification a fine grid has
been deposited on the chip surface by wafer post-processing (GridPix technology). The preciselyaligned grid holes and chip pixels having a pitch of 55 µm and the high time resolution of 1.56
ns of the Timepix3 chip enable the reconstruction of each individual ionization electron where
the accuracy is dominated by diffusion. The QUAD was designed to have minimum electrical field
inhomogeneities and distortions, achieving a tracking precision in the pixel plane with systematics
of better than 10 microns. Due to the high efficiency to detect the ionization electrons a precise
measurement of the energy loss dE/dx can be performed. The QUAD detector has all services
located under the detection surface. In this way multiple QUADs can be simply put together tocreate a detection surface of arbitrary dimensions. Using the 8 QUADs a module was constructedwith a readout system. The module was tested inside the PCMAG magnet in an electron beamat DESY in June 2021 where a silicon telescope was used to provide accurate tracking. In thepresentation details about the construction of the QUAD and module will be discussed. The resultsfrom the QUAD will be reviewed. An idea to improve the gating for a Gridpix device will bepresented. Simulation results for the performance of a full pixel TPC in ILD will be presented.
Finally, first preliminary results for the module in the DESY testbeam will be shown.

A new Readout Scheme of Gaseo ⋯タイプ: Oral presentation using Zoom

A new Readout Scheme of Gaseous Detectors
2021 年 10 月 28 日木曜日 19:20 (20 分)
A new readout scheme allowing the exploitation of Resistive Plate Chamber (RPC) spatial precisionand using a limited number of electronic channels is proposed. The new scheme which exploits
the spread of the RPC induced charge on several adjacent inter-connected pads, allows the simultaneous detection of several particles without ambiguity.
In this scheme, pads are connected in rows through buried vias in rear layers in an original way
so the charge induced by the passage of one particle is shared among pads belonging to different
directions. The pads of one row are connected to one electronic channel.
The position of the particle is determined by the intersection of the rows associated to the fired
pads and the ambiguity is eliminated by the fact that more than two crossing rows with two different directions are concerned.
The new scheme allows to instrument large detectors with a reduced number of electronics channels without reducing the spatial resolution obtained with pads read out individually.
We will present the results obtained on a cosmic ray bench built with 60 cm x 70 cm RPC read out
with the new readout scheme and we will discuss our plan to use the new scheme to instrument
large gaseous detectors.

2021 年 10 月 28 日木曜日 20:12 (24 分)
One of the challenges in times of preparing for a next large-scale collider is to properly modelits performance. For physical analyses, event generation of signal and background events is often
crucial to estimate discovery reach of the machine for New Physics. In many cases, not only should
beam collision background samples be analysed, but also there is a need to include background
events produced in other ways. At e+e- colliders, a significant part of the generated backgroundsamples can require usage of photon structure functions. Even though the ISR and EPA functions
are widely used for this purpose, one should be aware of their constraints. In my talk, I willshow why this issue can be important for ILC physics potential studies and I will present possible
approaches to merging of the structure functions with full matrix element calculations.

Carbon neutrality by 2050 is one of the most urgent issues in the world, and the ILC aiming to start
operation in 2035 should be in line with this global policy. The basic policy of Green ILC activities
is not to achieve carbon neutrality within the ILC facility, but to achieve carbon neutrality in theregion where the ILC is located. The key to achieving this goal is to cooperate with local companies
and municipalities in three areas: (1) developing energy-saving technologies, (2) increasing theratio of renewable energy, and (3) improving the CO2 absorption rate. The industrial aspect will
prevail in (1) and (2), but there is no choice but to rely on forests for (3). The area of the candidate
site has a high percentage of forest, and therefore high potential, so the construction of ILC-related
facilities should be in line with forest industry management that maximizes CO2 absorption.

ambitions, including computing. I will discuss the areas under review in the Snowmass computing
working group, issues of particular interest, timelines, and how to contribute to the process.

Homogeneous Hadron Calorimet ⋯タイプ: Oral presentation using Zoom

Homogeneous Hadron Calorimetry for superiordi-jet mass resolution
2021 年 10 月 27 日水曜日 14:12 (24 分)
One of the physics challenges for new detectors at an e+e- linear collider is to distinguish W
and Z vector bosons in their hadronic decay mode. This requires a di-jet mass resolution of theorder of the natural width of these bosons and hence a jet energy resolution of about 3%. For
hadron calorimetry this means that the required energy resolution be a factor of about two better
than previously achieved to date by any large-scale experiment. A novel approach to achieving
superior hadronic energy resolution is based on a homogeneous hadronic calorimeter (HHCAL)
detector concept, including both electromagnetic and hadronic parts, with separate readout of theCherenkov and scintillation light. By calibrating the dual readout response to electromagnetic
showers, the correlation between the Cherenkov and scintillation signals can be used to obtainsuperior hadronic energy resolution. This HHCAL detector concept has a total absorption nature,so its energy resolution is not limited by sampling fluctuations. It also has no traditional boundary
between the ECAL and HCAL, so it does not suffer from the effects of dead material in the middleof hadronic showers. With the dual-readout approach, measuring both Cherenkov and scintillator
light, the contribution to the energy resolution by large fluctuations in the determination of theelectromagnetic fraction of a hadronic shower can be vastly reduced. The missing nuclear binding
energy can then be corrected shower-by-shower, resulting in good energy resolution for hadronic
jets. In addition, by choosing optimal calorimeter cell sizes, particle flow techniques can be used tofurther improve the dual readout calorimeter performance. Active materials, such as scintillating
crystals, glasses or ceramics, may be used to construct an HHCAL.

A dual-readout electromagnetic calorimeter for
future e+e- Higgs factories
2021 年 10 月 27 日水曜日 13:00 (24 分)
In the past, homogeneous electromagnetic calorimeters have allowed precision measurements ofelectrons and photons, while high-granularity, dual-readout, and compensating calorimeters havebeen considered promising paths for improving hadronic measurements. In this talk, the possibility of using a homogeneous high-granularity crystal electromagnetic calorimeter using SiPMs
with a spaghetti hadronic calorimeter using clear and scintillating fibers is explored using simulation. By employing wavelength and timing measurements in both calorimeters, the excellent
electromagnetic resolution typical of crystal calorimeters is preserved, and the excellent hadronic
resolutions are enabled for important physics measurements at future Higgs factories. We also
discuss past studies and future plans.

RF power system of ILC by all ⋯タイプ: Oral presentation using Zoom

RF power system of ILC by all solid-state amplifiers.
2021 年 10 月 28 日木曜日 16:10 (20 分)
1300MHz Solid State Amplifier that can provide 200kW of 1.6m sec pulse width at 10pps max becomes available with reasonable cost. The latest LDMOS silicon semiconductor devices, NXP’s
800W-CW and 1600W-Pk devices, have been implemented and tested successfully.
This amplifier can feed each cavity, which eliminates the complex RF distribution system requiredfor high power Klystrons (MBKs). Though the LLRF system may become a little complex, the adjustments for cavities become independent, which will add a variety of flexibilities in the operation.

Kinematic fitting for ParticleFlow ⋯タイプ: Oral presentation using Zoom

Kinematic fitting for ParticleFlow Detectors at
Future Higgs Factories
2021 年 10 月 28 日木曜日 16:10 (20 分)
In many analyses in Higgs, top and electroweak physics, the kinematic reconstruction of the final
state is improved by constrained fits. This is a particularly powerful tool at e+ e− colliders, where
the initial state four-momentum is known and can be employed to constrain the final state. A
crucial ingredient to kinematic fitting is an accurate estimate of the measurement uncertainties,
in particular for composed objects like jets. This contribution will show how the particle flow
concept, which is a design-driver for most detectors proposed for future Higgs factories, can — inaddition to an excellent jet energy measurement — provide detailed estimates of the covariancematrices for each individual particle-flow object (PFO) and each individual jet. Combined withinformation about leptons and secondary vertices in the jets, the kinematic fit enables to correctb- and c-jets for missing momentum from neutrinos from semi-leptonic heavy quark decays. The
impact on the reconstruction of invariant di-jet masses and the resulting improvement in ZH vs
ZZ separation will be presented, using the full simulation of the ILD detector concept.

CP Violation in Higgs-τ − τ Coupling
2021 年 10 月 28 日木曜日 11:00 (20 分)
We demonstrate how probes of CP-violating observables in Higgs di-tau decays at prospective
future lepton colliders could provide a test of weak scale baryogenesis with significant discovery
potential. Measurements at the Circular Electron Positron Collider, for example, could exclude a
CP phase larger than 2.9◦ (5.6◦ ) at 68\% (95\%) C.L. assuming the Standard Model value for themagnitude of the tau lepton Yukawa coupling. Conversely, this sensitivity would allow for a 5σ
discovery for 82\% of the CP phase range [0,2π). The reaches of the Future Circular Collider-ee
and International Linear Collider are comparable. As a consequence, future lepton colliders could
establish the presence of CP violation required by lepton flavored electroweak baryogenesis withat least 3σ sensitivity. Our results illustrate that Higgs factories are not just precision machines
but can also make O(1) measurement of the new physics beyond the Standard Model.

Probing Extended Scalar Sectors with Precisione+e− → Zh and Higgs Diphoton Studies
2021 年 10 月 28 日木曜日 10:40 (20 分)
We compute the one-loop corrections to σ(e+ e− → Zh) arising from representative extended
Standard Model scalar sector scenarios. According to the new scalar SU(2)L representations,
we consider the inert doublet, real and complex triplet, quintuplet, and septuplet models. With
the sub-percent level precision expected for prospective future e + e− collider measurements ofσ(e+ e− → Zh), studies of the Higgsstrahlung process will probe extended scalar sector particle
spectrum and interactions in a manner complementary to direct searches at the Large Hadron
Collider and possible future pp colliders. We also compare with the sensitivity of future Higgs
diphoton decay rate measurements. We find that the σ(e+ e− → Zh) and Γ(h → γγ) complementarity is particularly pronounced for the complex triplet model.

We study the Higgs boson decays h -> c cbar, b bbar, b sbar, photon photon and gluon gluon in
the Minimal Supersymmetric Standard Model (MSSM) with general quark flavor violation (QFV),
identifying the h with the Higgs boson with a mass of 125 GeV. We compute the widths of theh decays to c cbar, b bbar, b sbar (s bbar) at full one-loop level in the MSSM with QFV. For the hdecays to photon photon and gluon gluon we compute the widths at NLO QCD level. We perform asystematic MSSM parameter scan respecting all the relevant constraints, i.e. theoretical constraints
from vacuum stability
conditions and experimental constraints, such as those from K- and B-meson data and electroweak
precision data, as well as recent limits on Supersymmetric (SUSY) particle masses and the 125 GeV

Conventional LGADs, of the type to be used in the timing layers of
the upgraded ATLAS and CMS detectors, are unable to provide granularity
finer than the millimeter scale. As a result, a number ofrefined approaches are under development to overcome limiting junction

as well as the status of R&D towards production of the first prototypes.

This talk summarizes a study of realistic design options for a far detector at the Belle II experiment,
dubbed GAZELLE. We have quantified the sensitivity of such a detector to long-lived particles
produced in e+e- collisions for three benchmark scenarios: axion-like particles, heavy neutral
leptons, and a dark matter scenario with a light scalar. GAZELLE will moderately improve thesensitivity to the couplings of these long-lived particles, compared to the excellent sensitivity of
the Belle II detector itself. Our general findings can help to design far detectors at the ILC, FCC-eeor CEPC.

Conventional muon beams are produced using proton beams and are used in material sciencessuch as µSR and elemental analysis, and fundamental physics experiments such as muon g-2 measurements and precision measurements of muoniums. These muon beams have high intensity but
poor emittance, and their kinetic energies are O(1) MeV. On the other hand, muon beams with alow emittance on the order of 10 GeV can be produced by using a high-energy electron/positron
beam at the ILC. This is expected to have a wide range of applications such as radiography of huge
structures, which has been conventionally performed with cosmic-ray muons, with high resolution using accelerator-generated muons. This talk will overview the way to produce muons fromelectron/positron beams at the ILC.

A cooling plate has been realized using Aluminum additive manufacturing. It was tested at DESY
using a TRACI closed-loop CO2 compressor ensuring a circulation of 2-phase CO2 under a pressure of 60 bars at a temperature of 19 degrees in a Micromegas TPC readout module.
The temperature of the front-end readout cards was continuously monitored for several days using
6 probes. This system allowed to lower the temperature of the electronic from 50 degrees to 24-26℃, and to maintain it with a stability of O(0.1 ℃) over several days.
Prospects for the cooling of the ILD TPC are addressed.

Pixel detector hybridization and i ⋯タイプ: Oral presentation using Zoom

Pixel detector hybridization and integration with
Anisotropic Conductive Films
2021 年 10 月 27 日水曜日 19:48 (24 分)
An alternative pixel-detector hybridization technology based on Anisotropic Conductive Films(ACF) is under development to replace the conventional fine-pitch flip-chip bump bonding. The
new process takes advantage of the recent progress in industrial applications of ACF and is suitable for time- and cost-effective in-house processing of single devices. This new bonding techniquedeveloped can also be used for the integration of hybrid or monolithic detectors in modules, replacing wire bonding or solder bumping techniques. This contribution introduces the new ACF
hybridization and integration technique, and shows the first test results from Timepix3 hybrid
pixel assemblies and from the integration of ALPIDE monolithic pixel sensors to flex circuits.

Development of iLGAD sensors at ⋯タイプ: Oral presentation using Zoom

Development of iLGAD sensors at IMB-CNM:
challenges and future applications
2021 年 10 月 27 日水曜日 19:00 (24 分)
In this contribution, we are going to present the last developments on Inverse Low Gain Avalanche
Detectors (iLGADs) at IMB-CNM. This iLGAD sensor concept is one of the most promising technologies for enabling the future 4D tracking paradigm that requires both precise position andtiming resolution. In the iLGAD concept, based on the LGAD technology, the readout is doneat the ohmic contacts, allowing for a continuous unsegmented multiplication junction. This architecture provides a uniform gain over all the active sensor area. This concept was successfully
demonstrated in a first generation of 300 μm thick iLGAD sensors. In the second
generation, we have fabricated thick iLGAD sensors optimizing the periphery for X-Ray irradiations. Currently, we are developing a third generation based on 50 μm thick pixelated iLGADs
optimized for timing detection, with a periphery designable to sustain high electric fields and a simpler single-side manufacturing process.
In addition, we are developing a new LGAD concept which is the Proton Low Gain Avalanche
Detector (pLGAD), which will be applied for low-energy particle detection.

Top, Higgs, Diboson and Electroweak Fit to theStandard Model Effective Field Theory
2021 年 10 月 29 日金曜日 13:00 (23 分)
The search for effective field theory deformations of the Standard Model (SM) is a major goal ofparticle physics that can benefit from a global approach in the framework of the Standard Model
Effective Field Theory (SMEFT). For the first time, we include LHC data on top production anddifferential distributions together with Higgs production and decay rates and Simplified Template
Cross-Section (STXS) measurements in a global fit, as well as precision electroweak and diboson
measurements from LEP and the LHC, in a global analysis with SMEFT operators of dimension 6
included linearly. We present the constraints on the coefficients of these operators, both individually and when marginalised, in flavour-universal and top-specific scenarios, studying the interplayof these datasets and the correlations they induce in the SMEFT. We then explore the constraints
that our linear SMEFT analysis imposes on specific ultra-violet completions of the Standard Model,
including those with single additional fields and low-mass stop squarks. We also present a modelindependent search for deformations of the SM that contribute to between two and five SMEFT
operator coefficients. In no case do we find any significant evidence for physics beyond the SM.
Our underlying
public code provides a framework for future generalisations of our analysis, including a quadratic treatment of dimension-6 operators.

New ideas for K/pi discrimination ⋯タイプ: Oral presentation using Zoom

New ideas for K/pi discrimination at the ILC
2021 年 10 月 27 日水曜日 20:12 (24 分)

One of the most interesting yet-to-be answered questions in Particle Physics is the nature of the
Higgs Yukawa couplings and their universality. Key information in our understanding of thisquestion arises from studying the coupling of the Higgs boson to second generation quarks. Somepuzzles in the flavor sector and potential additional sources of CP violation could also have their
origins in an extended Higgs sector.
Rare Higgs decay modes to charm or strange quarks are very challenging or nearly impossible todetect with the current experiments at the Large Hadron Collider, where the large multi-jet backgrounds inhibits the study of light quark couplings with inclusive h → ̄ decays. Future e+emachines are thus the perfect avenue to pursue this research.
Studies were initiated in the context of Snowmass2021 (https://indico.slac.stanford.edu/event/6617/contributions/1442/attach
EF1_EF2-IF3_IF0_Valentina_Maria_Martina_Cairo-047.pdf) with particular emphasis on the Higgs
coupling to strange quarks and the related flavour tagging challenges, which gave light to an interesting investigation of detector layouts. In this talk, we present a first examination of suitable
technologies, such as a modern ring imaging Cherenkov system, for ILC detectors to provide K/pi
discrimination in the momentum range needed for tagging strange-jets, with efficient rejection oflight-quark jets.

With the completion of the Standard Model, there is no guarantee that new particles can be foundat current or future colliders. Meanwhile, precision measurements of the Higgs and electroweakbosons at future lepton colliders offer a great opportunity for probing new physics beyond theStandard Model. The Standard Model Effective Field Theory (SMEFT) provides an ideal framework
for a model-independent interpretation of these measurements. In this talk, I will try to provide an
overview on the global SMEFT analyses at future lepton colliders, and highlight some of my own
work. I will discuss some interesting aspects of the analyses, such as the indirect determination of
the triple Higgs coupling via its loop contribution.

First we briefly introduce the basic concept of LUXE as an experiment. The proposed LUXE experiment (LASER Und XFEL Experiment) at DESY, Hamburg, using the 16.5 GeV electron beamfrom the European XFEL, aims to probe QED in the non-perturbative regime created in collisions
between high-intensity laser pulses and high-energy electron or photon beams. This setup also
provides a unique opportunity to probe physics beyond the standard model by a super efficient
way to convert an incoming electron flux to an amplified photon flux, which we denote as optical dump. This augmented by a physical dump, placed downstream the beam, allow us to probe
models of weakly interacting, spin-0 particles, coupled to photons with upercented precision at
the LUXE experiment.

Let’s measure the F2-gamma Structure -function
2021 年 10 月 27 日水曜日 20:15 (20 分)
A higher energy eplus-eminus collider than LEP should have a better luminometer , optimised tomeasure the acollinearity and energies of the leptons in Bhabha scattering events. Building upon
what we did with OPAL, such a luminometer could be used to make even more accurate measurements of Q-squared in deep-inelastic gamma-gamma scattering up to much higher values than LEP
could reach. A new central hadron detector would give better measurements of the invariant-masssquared W-squared of the recoiling hadrons and give better accuracy for x=Q-squared/(Q-squared+ W-squared).
The work still to be done includes writing and testing a Monte Carlo generator for fragmentationof the final state hadrons, so that the structure function can be unfolded from the observed distributions of x and Q-squared, in the way used by my former student Edmund Clay in the last of ourpublished OPAL F2-gamma analyses. His thesis is available as a ps.gz file on the UCL HEP groupwebsite. The only other extra work would be to write a simulation program for the performance ofthe luminometer as a tagger. The hard work for this may already have been done in optimising theluminosity measurement, maybe by Sailer from DESY, forCLIC. ILC ,CLIC or FCC eplus-eminus
should all be similar.

Tunnel Heat Recovery - Green ILC
2021 年 10 月 28 日木曜日 15:30 (20 分)
The drive to reduce carbon emissions and reliance on oil and gas has led to the increase in theuse of renewable energy heating systems. Ground source heat pump systems are an example ofthese renewable systems, and tunnels as a way of connecting building heat pump systems to theenergy stored in the soil and air. Thermal tunnel energy segments were designed on the Crossrail
project, London, UK. This demonstrated how energy consumption as well as CO2 emissions can be
reduced by such systems. This talk will discuss the challenges and opportunities for heat recovery
adoption in tunnels, including heat and ventilation interfaces, linking the tunnel heat to adjacentbuildings in cost effective ways, and the potential it could provide for green energy production on
major tunnelling projects such as ILC, CLIC and FCC. The context of this alongside other green
tunnelling initiatives which can contribute to net zero outcomes shall also be discussed.

The increase in efficiency of RF power generation for the future large-scale accelerators such as
CLIC, ILC, FCC, CEPC and others is considered as a high priority issue. The vast majority ofexisting commercial high RF power klystrons operates in the electronic efficiency range between
40% and 50%. Only a few klystrons available on the market are capable of operating with 65%
efficiency or above. Since 2014, a thorough High Efficiency (HE) klystron development program
was established at CERN. Specialized computer tools, different bunching technologies and klystron
topologies were studied and established since then and used for the development of different HE
klystrons. We will report on the HE klystron development status and CERN, and present a potential
candidate of the HE (85%) 10 MW L-band klystron for ILC.

Microchannel Cooling for LHCb

Microchannel Cooling for LHCb
2021 年 10 月 27 日水曜日 20:36 (24 分)
The LHCb vertex detector, VELO, is being upgraded for the LHC Run3. The new hybrid pixel vertex detector will be capable of 40 MHz readout and will be installed in the secondary vacuum of the
LHC at a closest proximity of 5.1 mm to the beams during stable collisions. The pixel detector requires a highly thermally efficient and lightweight cooling system. For this purpose a silicon platewith internal microchannels has been chosen as the backbone of the module, with evaporative
CO2 as the coolant. The reasons for this choice will be presented along with the principal development steps for the design, production and quality assurance of the microchannel plates. The
alternatives to microchannel cooling will be discussed along with an overview of cooling solutions
which could be considered for future upgrades.

Chronopixel Silicon CMOS Sensor ⋯タイプ: Oral presentation using Zoom

Chronopixel Silicon CMOS Sensor Development for
the ILC
2021 年 10 月 28 日木曜日 17:10 (20 分)
A monolithic silicon CMOS pixel detector with time-stamping capability (Chronopixel)has beendeveloped based on design goals of the International Linear Collider (ILC). Each hit is accompanied
by a time tag with sufficient precision to assign it to a particular ILC bunch crossing - thus thename Chronopixel. This reduces the occupancy to negligible levels, even in the innermost vertex
detector layer, yielding a robust vertex detector which operates at background levels significantly
in excess of those currently foreseen for the ILC. The Chronopixel can record and store time stamps
for two hits in each pixel while using standard CMOS processing for manufacturing. Following
two earlier prototype fabrication runs and tests, a third prototype design was developed to resolve
earlier issues, including a high capacitance problem. This problem was traced to the TSMC 90 nm
technology design rules, which led to an unacceptably large value of the sensor diode capacitance.
Six different layouts for the sensor diode were tested in the third prototype, and tests demonstrated
that the high capacitance problem was solved. The third prototype has also been exposed to HLLHC radiation levels; results of these tests are also presented. Simulation of the signal formationfrom charge particle crossing detector with one particular sensor design also was done and results
will be shown.

Precision Z physics at the LHC in the flavorful
SMEFT
2021 年 10 月 29 日金曜日 13:46 (16 分)
We study the forward-backward asymmetry AF B in pp → l+ l− at the Z peak within the Standard Model Effective Field Theory (SMEFT). We find that this observable provides per mille level
constraints on the vertex corrections of the Z boson to quarks, which close a flat direction in theelectroweak precision SMEFT fit. Moreover, we show that current AF B data is precise enough sothat its inclusion in the fit improves significantly LEP bounds even in simple New Physics setups.
This demonstrates that the LHC cancompete with and complement LEP when it comes to precision measurements of the Z boson
properties.
