Reactor antineutrino anomaly revisited circa 2021
Authors: Xin Z. 
Published: February 2022

Abstract
In our recent work [1], we study the status of the reactor antineutrino anomaly in light of new reactor flux conversion and summation models. We present a new improved calculation of the IBD yields of the standard Huber-Mueller (HM) model and those of the new models. We show that the reactor rates and the fuel evolution data are consistent with the predictions of the Kurchatov Institute (KI) conversion model and with those of the Estienne-Fallot (EF) summation model, leading to a plausible robust demise of the reactor antineutrino anomaly. We also show that the results of several goodness of fit tests favor the KI and EF models over other models under consideration.
Search for Supernova Relic Neutrinos at KamLAND
Authors: Obara S , Ieki S , Ishidoshiro K , Mitsui T , Watanabe H , Decowski M P 
Published: February 2022

Abstract
We report a search for electron antineutrinos at KamLAND with an 8.3−30.8 MeV energy range via the inverse beta decay. In 6.72 kton-yr of KamLAND data, we found 18 neutrino candidates and no significant excess over estimated backgrounds. From data interpretation, with the assumption of some supernova relic neutrino spectrum predictions, we give upper flux limits of 60−110 cm−2 s−1 (90% CL) in the analysis range and present a model-independent flux. These upper limits are the most stringent for 8−13 MeV region. We also improve on the upper probability limit of 8B solar neutrinos converting into antineutrinos via the Resonant Spin Flavor Precession with the neutrino magnetic moment. Besides, we could set limits on the annihilation cross-section for light dark matter pairs to neutrino pairs.
Short-Baseline neutrino oscillation searches with the ICARUS detector
Authors: Farnese Christian 
Published: February 2022

Abstract
The ICARUS collaboration employed the 760-ton T600 detector in a successful three-year physics run at the underground LNGS laboratories studying neutrino oscillations with the CNGS neutrino beam from CERN, and searching for atmospheric neutrino interactions. ICARUS initially performed a sensitive search for LSND-like anomalous υ
e appearance in the CNGS beam constraining the allowed parameters to a narrow region around 1eV
2. After a significant overhauling phase at CERN, the T600 detector was installed at Fermilab and activated in 2020 in view of the forthcoming sensitive search for sterile neutrinos using the Booster beam within the Short Baseline Neutrino (SBN) program. During the initial commissioning phase ICARUS already collected the first neutrino events from the Booster Neutrino Beam and the NuMI off-axis. The proposed contribution will address ICARUS achievements, its status and plans for the new run at Fermilab.

Abstract
We study a strategy to reduce veto-time in the search for neutrino-less double-beta decay (0υββ) with CANDLES-III system. We develop a new likelihood analysis and apply it to our new Run010 data. We show that we can increase the un-vetoed live-time by 11.8%. Thanks to this improvements, We expect to increase a limit on the life-time of 0υββ by a factor of three by analyzing both Run009 and Run010 data.
Study of tau neutrino production with nuclear emulsion at CERN-SPS
Authors: Vasina S. 
Published: February 2022

Abstract
The tau neutrino interaction cross-section was directly measured in the DONuT experiment but it suffers from a large systematic (∼50%) and statistical (∼30%) errors. The main source of the systematic error was due to poor knowledge of the tau neutrino flux. The DsTau experiment at CERN-SPS has been proposed to measure an inclusive differential cross-section of the Ds
production with a consecutive decay to tau lepton in p-A interactions, which is a main source of tau neutrinos in neutrino beams at accelerators. The search for Ds
→ τ → X decay is challenging due to milimetric range of Ds
and τ decay lengths and a small angle between them of the order of few mrad. Nevertheless a precise measurement is possible with the use of nuclear emulsion providing a sub-micron spatial resolution. The experiment is aiming to collect 2.3 × 108 proton interactions in the tungsten target, and to detect ∼ 1000 Ds
→ τ → X decays. DsTau successfully performed a pilot run in 2018 collecting ∼10% of the full data and was approved as NA65 in 2019. The results from the pilot run are presented in this paper and the prospect for physics runs in 2021–2022 are given.
Status of Super-Kamiokande Gadolinium project
Authors: Ikeda Motoyasu 
Published: February 2022

Abstract
Super-Kamiokande (SK) is the world’s largest underground water Cherenkov detector. The latest phase of operations began in July 2020 when, in order to improve neutron detection efficiency, about 13 tons of gadolinium (Gd) sulfate octahydrate was dissolved into SK’s pure water. Gd has a large thermal neutron capture cross section and emits visible gamma rays. This first loading marked the start of what is now called SK-Gd, and stable physics data taking has been ongoing since then. This presentation will focus on details of the first Gd loading and the detector status including detector calibrations. Also, the future plan and the prospect of observations with SK-Gd will be discussed.
The role of leptonic CPV phases in cLFV observables
Authors: Kriewald J , Abada A , Teixeira A M 
Published: February 2022

Abstract
In models where the Standard Model is extended by Majorana fermions, interference effects due to the presence of CP violating phases have been shown to play a crucial role in lepton number violating processes. However, important effects can also arise in lepton number conserving, but charged lepton flavour violating (cLFV) transitions and decays. Here we show that the presence of CP violating (Dirac and Majorana) phases can have a striking impact for the predicted rates of cLFV observables. We explore the interference effects in several cLFV observables, carrying for the first time a thorough analysis of the different observables and the implications for future observation. We discuss how the presence of leptonic CP violating phases might lead to a loss of correlation between observables (typically present in simple SM extensions via heavy sterile fermions), or even to the suppression of certain channels; these effects can be interpreted as suggestive of non-vanishing phases.
Dark matter Axion search with riNg Cavity Experiment DANCE: Design and development of auxiliary cavity for simultaneous resonance of linear polarizations
Authors: Fujimoto Hiroki , Oshima Yuka , Ando Masaki , Fujita Tomohiro , Michimura Yuta , Nagano Koji , Obata Ippei 
Published: February 2022

Abstract
Axion-like particles (ALPs) are undiscovered pseudo-scalar particles that are candidates for ultralight dark matter. ALPs interact with photons slightly and cause the rotational oscillation of linearly polarized light. Dark matter Axion search with riNg Cavity Experiment (DANCE) searches for ALP dark matter by amplifying the rotational oscillation with a bow-tie ring cavity. Simultaneous resonance of linear polarizations is necessary to amplify both the carrier field and the ALP signal, and to achieve the design sensitivity. The sensitivity of the current prototype experiment DANCE Act-1 is less than expectation by around three orders of magnitude due to the resonant frequency difference between s- and p-polarization in the bow-tie ring cavity. In order to tune the resonant frequency difference, the method of introducing an auxiliary cavity was proposed. We designed an auxiliary cavity that can cancel out the resonant frequency difference and realize simultaneous resonance, considering optical loss. We also confirmed that the sensitivity of DANCE Act-1 with the auxiliary cavity can reach the original sensitivity.
Measurement of cosmogenic neutron production in SK-Gd
Authors: Shinoki Masataka 
Published: February 2022

Abstract
The Super-Kamiokande-Gd (SK-Gd) experiment has started after adding the gadolinium (Gd) into ultra-pure water in the SK detector. SK-Gd dramatically improves the sensitivity to supernova relic neutrino searches by tagging neutrons. Cosmic-ray muons penetrating into the SK detector induce hadronic showers. Such muon often break oxygen nuclei in water and produce unstable radioactive isotopes and neutrons, which are major background sources for supernova relic neutrino searches. On the other hand, the cosmogenic neutrons produced by muons can be used for the detector calibration source. Since cosmic-ray muons penetrate into the SK detector continuously with the rate of 2 event/s, the cosmogenic neutrons can be used to monitor the stability and uniformity of the Gd concentration in water. In this proceeding, we report the progress of cosmogenic neutron measurement in SK-Gd.

Abstract
The new method for correcting the charge signal from the large proportional counter is proposed. The correction method makes possible to consider the loss of primary ionization electrons in the presence of weakly increasing microimpurities of electronegative gases during long-term measurements. It allows increasing the efficiency of the selection of useful events and thereby increasing the sensitivity to 2ν2K-decay in 124Xe at the level of 2 × 1022 y from over six years of measurements using a large proportional counter. Analysis of the calibration data, taking into account a new method for correcting the energy release in the detector, made it possible to register events from double K photoionization by a single photon.

Abstract
Objectives of the TAIGA Astrophysical complex include the study of the flux of charged cosmic rays and diffuse gamma rays with energies above 100 TeV. This complex is located in the Tunka Valley about 50 km from Lake Baikal at the site of the Tunka-133 Cherenkov facility. TAIGA includes the TAIGA-HiSCORE wide-angle Cherenkov array, the network of Imaging Atmospheric Cherenkov Telescopes (TAIGA-IACT), the Tunka-Grande and TAIGA-Muon scintillation arrays. In this work, we present the results of an analysis of the joint events of the Tunka-Grande scintillation array and TAIGA-HiSCORE and Tunka-133 Cherenkov facilities. The results verify sufficient accuracy of the scintillation experiment for the hybrid study of mass composition of cosmic rays and gamma-hadron separation.
Implementation of IceTop data in the IceCube Realtime Alert System
Authors: Amin Najia Moureen Binte 
Published: February 2022

Abstract
The IceCube Neutrino Observatory is a cubic-kilometer detector at the geographic South Pole searching for astrophysical neutrinos. The main background for astrophysical neutrinos is leptons produced by cosmic ray air showers: neutrinos from the northern hemisphere and muons from the southern hemisphere. These atmospheric backgrounds are reduced using a data-driven selection based on the observed event energy and arrival direction. An array of ice-Cherenkov tanks on the surface, IceTop, detects showers of secondary particles created in cosmic ray air showers. We will show that data from IceTop can be used to further reduce the background due to atmospheric muons, and by implementing this method, we vetoed three alert events.
Electromagnetic effects in elastic neutrino scattering on nucleons
Authors: Kouzakov Konstantin , Lazarev Fedor , Studenikin Alexander 
Published: February 2022

Abstract
We study the electromagnetic contribution to elastic neutrino-proton and neutrino-neutron scattering processes. The neutrino electromagnetic charge, magnetic, electric, and anapole form factors of both diagonal and transition types in the mass basis are taken into account in the present formalism. When treating the nucleon electromagnetic vertex, we take into account not only the charge and magnetic form factors of a nucleon, but also its electric and anapole form factors. We examine how the effects of the neutrino millicharge can be disentangled from those of the strange quark contributions to the nucleon’s weak neutral current form factors.

Abstract
The CRESST experiment searches for dark matter induced nuclear recoils inside CaWO4 based cryogenic calorimeters at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. To identify reliably a potential signal, a precise understanding of its background budget is crucial. An important background category could be “cosmogenics”: radionuclides produced via interactions with cosmic rays, mainly during the crystal production at surface facilities. Albeit CaWO4 is a well-established calorimetric material, no systematic study of its susceptibility for cosmic activation existed so far. In this contribution, we will first report the exposure profile of CRESST’s in-house grown TUM93 crystal to cosmic rays. Then we will identify the most prominent cosmogenics via AcTIVIA calculations. Afterwards we discuss the expected background spectrum based on Geant4 simulations and compare it to measurements.
Dirac and Majorana neutrino oscillations in magnetized moving and polarized matter
Authors: Abdullaeva Umsalimat , Shakhov Vadim , Studenikin Alexander , Tsvirov Alexander 
Published: February 2022

Abstract
In the present paper we develop the quantum theory of neutrino spin and spin-flavour oscillations in moving magnetized matter with a special focus on the effects of matter polarization. We derive an effective neutrino evolution Hamiltonian and corresponding expressions for the neutrino oscillation probabilities. Both the case of Dirac and Majorana neutrinos are considered. From the comparison of the neutrino spin oscillation probabilities in the transversally moving matter for the Dirac and Majorana neutrinos it follows that the oscillation patterns is different for theses two cases. In particular, the conditions for the resonances in these two cases are realized at different densities of matter.
Prospects for searching new Double Beta Decay physics with KamLAND-Zen 800
Authors: Yuto Kamei 
Published: February 2022

Abstract
Two-neutrino double beta decay (2υββ) is a rare second-order weak radioactive decay process. It has been observed in neutrinoless double beta decay (0υββ) search experiments. Precise observation of 2υββ is essential to reduce the theoretical uncertainty in the calculation of nuclear matrix elements required to obtain the effective Majorana mass from a lifetime of 0υββ. Also, 2υββ itself is interesting because new physics could be hiding in the energy spectrum, such as for example, Majoron emission mode 0υββ and 2υββ with neutrino self-interaction. KamLAND-Zen 800 is an experiment to search for 0υββ of 136Xe with a large ultra-pure liquid scintillator detector, KamLAND. KamLAND-Zen 800 has been observing 745 kg of xenon gas at 91% enriched in 136Xe since 2019, providing a high statistics 2υββ decay sample. We describe the potential for new physics searches in 2υββ with KamLAND-Zen 800.

Abstract
In the past few years, attention has been drawn to the fact that a precision analysis of two-neutrino double beta decay (2υββ) allows the study of interesting physics cases like the emission of Majoron bosons and possible Lorentz symmetry violation. These processes modify the summed-energy distribution of the two electrons emitted in 2υββ. CUPID is a next-generation experiment aiming to exploit 100Mo-enriched scintillating Li2MoO4 crystals, operating as cryogenic calorimeters. Given the relatively fast half-life of 100Mo 2υββ and the large exposure that can be reached by CUPID, we expect to measure with very high precision the 100Mo 2υββ spectrum shape, reaching great sensitivities in the search for distortions induced by the physics beyond the Standard Model. In this contribution, we present the CUPID exclusion sensitivity for such New Physics processes, as well as the preliminary projected background of CUPID.
Role of Charged Scalar in Icecube and NSI
Authors: Sadhukhan Soumya 
Published: February 2022

Abstract
We study a variant of neutrinophilic two-Higgs doublets model to explain excess neutrino events in the 1 – 3 PeV energy bins at the IceCube. This is arranged by a charged scalar in the model, through a Glashow-like resonance. The same charged scalar can generate sizeable non standard interactions (NSIs) of the neutrinos. We perform a combined analysis of the latest IceCube observations, taking into account constraints from the neutrino and LEP experiments, to explore the parameter space leading to sizeable NSIs.
Setting limits on heavy neutral leptons using the neutrino CC events at the DUNE near detector
Authors: Carbajal S , Gago A M 
Published: February 2022

AbstractWe study the impact of production of heavy neutral leptons (HNL) from meson decays on the number of neutrino charged current (CC) events that will be detected at the DUNE ND LArTPC. If the masses of the HNLs are below the kaon mass, then a decreased number of CC events at the DUNE LArTPC will be observed. This decrease is used to set upper limits on the mixing parameters of the HNLs. We find that these limits are at least 1 order of magnitude better than the current ones for masses below 1 MeV for a year of operation in neutrino mode.

Abstract
The fast timing MPGD is a micro-pattern gaseous detector conceived for achieving sub-nanosecond time resolution while maintaining the ability to instrument large areas in high-rate environments; applications of such technology are perspected in high-energy physics experiments at future colliders and medical diagnostics with time-of-flight methods. The work presented is a set of systematic studies carried on an FTM prototype on the performance of GEM foils coated with resistive DLC films, whose development is essential for the FTM operation. The resistive foil performance has been tested with several gas mixtures and compared with the results obtained on conductive foils. The results show that the performance of the FTM is presently limited by the technology of manufacturing of DLC-coated GEM foils, with high gains reachable exclusively in isobutane-based mixtures.
