Massive neutrino self-interactions and the Hubble tension
Authors: Choudhury Shouvik Roy , Hannestad Steen , Tram Thomas 
Published: February 2022

Abstract
We consider flavour independent neutrino self-interactions among massive neutrinos mediated by a heavy scalar against cosmological data. Such a model had previously shown to have potential in completely resolving the Hubble tension for the very strong interaction case with coupling strength ∼ 109 times the Fermi constant, by delaying the onset of neutrino free-streaming until matter-radiation equality. Our cosmological model consists of a total nine parameters which includes the six ACDM parameters and three parameters related to neutrinos: sum of neutrino masses (Σmν
), neutrino energy density (Neff
), and the effective coupling strength, log10 [GeffMeV2]. With the latest CMB data from the Planck 2018 data release as well as auxiliary data, we find that the region in parameter space with such strong interactions is still present in the posterior distribution. However, high-l polarisation data from the Planck 2018 release disfavours this strongly interacting mode even though it cannot yet be excluded. Our resuts show that the neutrino mass bounds obtained from cosmological data remain robust against when considering neutrino self-interactions. We also find that the high-l polarisation data also does not allow for high values of H
0 that can solve the current Hubble discrepancy, i.e. this model is not a viable solution to the same.
Crystal responses to general dark matter-electron interactions
Authors: Urdshals Einar 
Published: February 2022

Abstract
In [1] we develop a non-relativistic effective field theory (NR-EFT) based framework with which rates of dark matter (DM) induced electron hole pair creation in silicon and germanium crystals can be obtained for any form of non-relativistic DM-electron interactions with spin 1/2 DM. We find that the crystal physics is captured by 5 crystal response functions, 4 of which are novel to that work, and we evaluate them using a state of the art DFT calculation.
MADMAX: a QCD dark matter axion direct-detection experiment
Authors: Lee Chang , LiJ Xiaoyue , Strom Derek , Reimann Olaf 
Published: February 2022

Abstract
Peccei and Quinn proposed axions to solve the strong CP problem. Axions later turned out to be an excellent candidate for cold dark matter. They may have a mass of around 100 μeV if generated after cosmic inflation. The MADMAX collaboration aims to detect post-inflationary QCD axion using a new detector concept, the dielectric haloscope. It detects axion-induced traveling waves from boundaries of different media, boosted by layers of dielectrics. We report the current progress and future measurement plan for a proof-of-principle setup. We also report the current development of the prototype detector and the full MADMAX experiment.

Abstract
Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed to search for axion dark matter [Phys. Rev. Lett. 121, 161301 (2018)]. We aim to detect the rotation and oscillation of optical linear polarization caused by axion-photon coupling with a bow-tie cavity. DANCE can improve the sensitivity to axion-photon coupling constant gaγ

for axion mass ma < 10−10 eV by several orders of magnitude compared to the best upper limits at present. A prototype experiment DANCE Act-1 is ongoing to demonstrate the feasibility of the method and to investigate technical noises. The optics was assembled and the performance of the cavity was evaluated. The first 12-day observation was successfully performed in May 2021. We reached

New Results from a Three-Year Annual Modulation Search with COSINE-100
Authors: Thompson WG 
Published: February 2022

Abstract
COSINE-100 is a direct detection dark matter experiment that is testing DAMA/LIBRA’s claim of dark matter discovery. Located in South Korea’s Yangyang underground laboratory, C0SINE-100 comprises 106 kg of sodium iodide detectors surrounded by a ∼2000 L liquid scintillator veto. In this talk, I will present new results from an annual modulation search using three years of data and the impact on DAMA/LIBRA’s discovery claim. I will also discuss improvements over our previous modulation analysis, including lowering the analysis threshold to 1 keV and the development of a more robust time-dependent background model. In addition, I will review ongoing R&D projects for, and the physics reach of future phases of the experiment.
Ultralight dark matter: constraints from gravitational waves and other astrophysical observations
Authors: Poddar Tanmay Kumar 
Published: February 2022

Abstract
The orbital period loss of the compact binary systems is the first indirect evidence of gravitational waves which agrees well with Einstein’s general theory of relativity to a very good accuracy. However, there is less than one percent uncertainty in the measurement of orbital period loss from the general reltivistic prediction. Perihelion precession of planets, Gravitational light bending and Shapiro delay are three other successful tests of general relativity theory. Though there are uncertainties in the measurements of those observations from the general reltivistic predictions as well. To resolve these uncertainties, we assume radiation of ultralight axions and light gauge boson particles of L
i
– Lj
type from those systems which can be a possible candidate of fuzzy dark matter. In this article, we obtain bounds on new physics parameters from those astrophysical observations.
Searching for Dark Matter with the PADME experiment
Authors: Oceano Isabella 
Published: February 2022

Abstract
The great success of the Standard Model has reached its maximum with the Higgs boson discovery. However, several anomalies observed in the universe when applying the gravitational theory, lead to believe that the visible matter is not the only constituent of the universe. A new matter component, called dark matter, must be introduced through an extension of the Standard Model. A simple scenario consisting in adding a new gauge symmetry U
D (1) and, as a consequence, a new (massive) gauge boson, the dark photon A′. PADME is a new experiment of the Laboratori Nazionali di Frascati searching for the A′, decaying invisibly, produced in the fixed target annihilation e+e
− → γA′. The technique used by the experiment to probe the dark photon hypothesis is the missing mass method. The PADME experiment took data in two runs. Some preliminary highlights from the ongoing data analysis effort are presented.
The impact of operator interference and target complementarity in dark matter direct detection experiments
Authors: Brenner Anja , Herrera Gonzalo , Ibarra Alejandro , Kang Sunghyun , Rappelt Andreas , Scopel Stefano , Tomar Gaurav 
Published: February 2022

Abstract
We present a method to determine the limits on the DM-nucleon interaction strengths for one experiment in the non-relativistic effective theory by taking the interference of operators into account. Further, we extend the method to combine several experiments. To apply the developed methods, we use data from the XENON1T and PICO6O collaborations. The relaxation caused by the interference among operators can be up to four orders of magnitude. The strengthening of the limits by combining the analysis of both experiments can be up to four orders of magnitude.

Abstract
The Dark Matter Daily Modulation experiment (DMSQUARE) seeks for dark matter interactions with a Skipper CCD. It is currently running at surface level in Bariloche, Argentina, and will be moved to a shallow underground site at Sierra Grande, Argentina in November 2021. The low threshold achieved by Skipper CCDs allows to search for electron recoil events with an ionization energy down to 1.2 eV. In order to extract a potential dark matter signal from noise at the single electron level, we propose to search for a diurnal modulation of events, resulting from the potential interaction of the dark matter wind with the particles in the Earth. Depending on the model, mass and cross-section, this modulation can be maximum at 40deg of latitude in the Southern Hemisphere, where DMSQUARE is operated. In this article we present the experiment, report preliminary results with a prototype Skipper CCD taking data at surface level and comment on future prospects.
Finding the Ultralight Boson from a Black Hole’s Ringdown
Authors: Gais Joseph , Chung Adrian Ka-Wai , Cheung Mark Ho-Yeuk , Li Tjonnie G.F. 
Published: February 2022

Abstract
Solving the problem of dark matter remains one of the greatest unsolved mystery of fundamental physics. One possible dark matter candidate is the scalar ultralight boson, with mass « 1eV. If they exist, ultralight bosons will form clouds of significant total mass about rotating black holes, affecting the spacetime around the black hole. After the inspiral phase of a binary merger, the bosonic cloud can affect the perturbations to the black hole, resulting in deviations in the quasinormal mode frequencies of the ringdown signal of a binary merger. Here, we compute these shifts in the gravitational quasinormal mode frequencies for such a system, and conduct an injection campaign with supermassive black holes detected by the Laser Interferometer Space Antenna. We find that detections of the ringdown phase of supermassive black holes can rule out or confirm the existence of cloud-forming ultralight bosons of mass ∼ 10−18eV at redshift z > 1 if cloud dissipation effects during the inspiral can be neglected.

Abstract
The coherent WaveBurst (cWB) pipeline implements a minimally-modelled search to find a coherent response in the network of gravitational wave detectors of the LIGO-Virgo Col-laboration in the time-frequency domain. In this manuscript, we provide a timely introduction to an extension of the cWB analysis to detect spectral features beyond the main quadrupolar emission of gravitational waves during the inspiral phase of compact binary coalescences; more detailed discussion will be provided in a forthcoming paper [1]. The search is performed by defining specific regions in the time-frequency map to extract the energy of harmonics of main quadrupole mode in the inspiral phase. This method has already been used in the GW190814 discovery paper (Astrophys. J. Lett. 896 L44). Here we show the procedure to detect the (3, 3) multipole in GW190814 within the cWB framework.
High-Energy Neutrinos from Starburst galaxies: implications for neutrino astronomy
Authors: Ambrosone Antonio , Chianese Marco , Fiorillo Damiano F.G. , Marinelli Antonio , Miele Gennaro , Pisanti Ofelia 
Published: February 2022

Abstract
Starburst and Starforming galaxies are astrophysical sources characterised by an intense star-forming activity. They are reservoirs of cosmic rays and host a high density target gas in the central region called Starburst Nucleus (SBN). In this contribution, we present the results of two model studies regarding the high-energy neutrino production. For the first one, we perform a diffuse analysis. In particular, we consider a blending of spectral indexes and obtain a multi-component description of extragalactic background light (EGB), high energy starting events (HESE) and high-energy cascade IceCube data. Remarkably, we find that, differently from recent prototype scenarios, the spectral index blending allows starburst galaxies to account for up to 40% of the HESE events at 95.4% CL and favors a maximal energy of the accelerated cosmic rays at teens of PeV. For the second one, we present a point-like analysis regarding nearby SFGs. We apply the calorimetric approach to the known SBGs within 100 Mpc, considering, were possible, a source-by-source description of the star formation rate. These results are then compared with what IceCube has observed at TeV energies as well as with what can be expected from the incoming KM3NeT and IceCube gen 2.
On the interpretation of the latest AMS-02 cosmic ray electron spectrum
Authors: Donato Fiorenza 
Published: February 2022

Abstract
The latest AMS-02 data on cosmic ray electrons show a break in the energy spectrum around 40 GeV, with a change in the slope of about 0.1. We perform a combined fit to the newest AMS-02 positron and electron flux data above 10 GeV using a semi-analytical diffusion model where sources includes production of pairs from pulsar wind nebulae (PWNe), electrons from supernova remnants (SNRs) and both species from spallation of hadronic cosmic rays with interstellar medium atoms. We demonstrate that within our setup the change of slope in the AMS-02 electron data is well explained by the interplay between the flux contributions from SNRs and from PWNe. In fact, the relative contribution to the data of these two populations changes by a factor of about 13 from 10 to 1000 GeV. The PWN contribution has a significance of at least 4σ, depending on the model used for the propagation, interstellar radiation field and energy losses. We checked the stability of this result against low-energy effects by solving numerically the transport equation, as well as adding possible breaks in the injection spectrum of SNRs. The effect of the energy losses alone, when the inverse Compton scattering is properly computed within a fully numerical treatment of the Klein-Nishina cross section, cannot explain the break in the e− flux data, as recently proposed in the literature.

Abstract
Recent observations by TA and Auger have advanced our understanding of ultra-high energy cosmic rays, but their origin is still unclear. As a future approach, it will be effective to obtain the directional energy spectra and compositional distributions by observing even larger statistics, and there are active discussions on future large-scale experiments. In order to realize such a huge observation area, the Cosmic Ray Air Fluorescence Fresnel lens Telescope (CRAFFT) project has started to develop a cost-effective fluorescence telescope with Fresnel lenses. We have succeeded in observing cosmic ray induced air showers by simultaneous observations with TA using prototype telescope. We are currently working on the development of an event reconstruction method using waveforms, optimization of the focal plane, development of a calibration system, and development of an autonomous observation system for future large-scale deployment. The current status and future prospects of the CRAFFT project are discussed.
Using PIC-MHD to model the interaction between an electron-positron beam and a thermal plasma
Authors: Marle Allard Jan van , Marcowith Alexandre , Plotnikov Illya , Guepin Claire 
Published: February 2022

Abstract
The origin of the gamma-ray halo around pulsars is associated with the reduced diffusivity of energetic particles responsible for gamma-ray emission with respect to the mean-free path they adopt in the interstellar medium. A possible explanation for this behaviour is that the energetic particles released from the pulsarwind termination shock themselves trigger the turbulence necessary to explain this reduced diffusivity. In order to test the ability of the electron-positron beam to trigger an efficient streaming instability we are in the process of conducting a series of b simulations using both the PIC-MHD technique to follow the evolution of both the electron-positron beam and the thermal background plasma and determine whether the beam can trigger the necessary instabilities. We find that the passage of the electron-positron beam through the thermal plasma triggers streaming instabilities that lead to local amplification of the magnetic field.
A generalization of the Scotogenic model
Authors: Escribano Pablo 
Published: February 2022

Abstract
The Scotogenic model is a radiative neutrino mass model able to induce Majorana neutrino masses at the 1-loop level and simultaneously include a dark matter candidate. In this work, we generalize the original Scotogenic model to arbitrary numbers of generations of the Scotogenic states. After that, we present the light neutrino mass matrix, with some details of its derivation, and provide a useful approximate expression as well. Finally, we numerically solve the Renormalization Group Equations to explore the high-energy behavior of the model. 1
KM3NeT: status and perspectives for neutrino astronomy from the MeV to the PeV
Authors: Celli Silvia 
Published: February 2022

Abstract
KM3NeT is a multi-purpose neutrino observatory, being currently deployed at the bottom of the Mediterranean Sea. It consists of two detectors: ORCA and ARCA (for Oscillation and Astroparticle Research with Cosmics in the Abyss, respectively). ARCA will instrument 1 Gton of seawater, with the primary goal of detecting cosmic neutrinos with energies between several tens of GeV and PeV. Due to its position in the Northern Hemisphere, ARCA will provide an optimal view of the Southern sky, including the Galactic Center. In April 2021, a major step has be taken in the construction of ARCA, bringing the number of detection lines from one to six. ORCA, also currently running in a six-string configuration, is a smaller (∼ few Mtons) and denser array, optimized for the detection of atmospheric neutrinos in the 1 — 100 GeV. It can also perform low-energy neutrino astronomy studies, e.g. searching for MeV-scale neutrinos expected at core-collapse supernovae. In this contribution, some of the key scientific cases in the field of neutrino astronomy are reviewed and perspectives for their investigation with KM3NeT are presented.

Abstract
Coherent elastic neutrino-nucleus scattering (CEνNS) offers a unique way to study neutrino properties and to search for new physics beyond the Standard Model. The NUCLEUS experiment aims to measure CEνNS of reactor anti-neutrinos down to unprecedented low nuclear recoil energies. The novel gram-scale cryogenic detectors feature an ultra-low energy threshold of ≤20eVnr and a rise time of a few 100 μs which allows the operation above ground. The fiducialization of the detectors provides an effective discrimination of ambient γ- and surface backgrounds. Furthermore, the use of multiple targets promises a high physics potential. The NUCLEUS experiment will be located at a new experimental site at the Chooz nuclear power plant in France, providing a high anti-neutrino flux of

Primordial Black Holes evaporating on the neutrino floor
Authors: Calabrese Roberta 
Published: February 2022

Abstract
Primordial Black Holes (PBHs) are Black holes formed in the early universe. They evaporate emitting all the elementary particles whose mass is lower than the PBHs temperature. We focused on PBHs whose mass is the range [5 × 1014, 8 × 1015]g. We studied their neutrinos emission. These neutrinos can interact via coherent elastic neutrino-nucleus scattering (CEvNS) producing a signal in multi-ton DM direct detection experiments. We show that is possible to set bounds on the PBHs abundance. This talk is based on Ref.[1].

ESSnuSB is a unique future proposed long-baseline experiment in Sweden to study neutrino oscillation by probing the second oscillation maximum. In this proceeding, we update the flux and efficiencies and re-calculate the sensitivity of ESSnuSB in the standard three flavour scenario. We find that it has excellent sensitivity to the Dirac CP phase δCP, moderate sensitivity to the mass hierarchy of the neutrinos and limited sensitivity to measure the octant of the atmospheric mixing angle θ
23. We also find that it has a very good sensitivity to constrain the atmospheric mass squared difference

Simulation of Nuclear Recoils due to Supernova Neutrino-induced Neutrons in Liquid Xenon Detectors
Authors: Ghosh Sayan , Bandyopadhyay Abhijit , Bhattacharjee Pijushpani , Chakraborty Sovan , Kar Kamales , Saha Satyajit 
Published: February 2022

Abstract
Neutrinos from supernova (SN) bursts can give rise to detectable number of nuclear recoil (NR) events through the coherent elastic neutrino-nucleus scattering (CEυNS) process in large scale liquid xenon detectors designed for direct dark matter search, depending on the SN progenitor mass and distance. Here we show that in addition to the direct NR events due to CEvNS process, the SN neutrinos can give rise to additional nuclear recoils due to the elastic scattering of neutrons produced through inelastic interaction of the neutrinos with the xenon nuclei. We find that the contribution of the supernova neutrino-induced neutrons (υIn) can significantly modify the total xenon NR spectrum at large recoil energies compared to that expected from the CEυNS process alone. Moreover, for recoil energies ≳ 20 keV, dominant contribution is obtained from the (υIn) events. We numerically calculate the observable S1 and S2 signals due to both CEvNS and vIn processes for a typical liquid xenon based detector, accounting for the multiple scattering effects of the neutrons in the case of υIn, and find that sufficiently large signal events, those with S1≳50 photo-electrons (PE) and S2≳2300 PE, come mainly from the υIn scatterings.
Separation of the 235U and 239Pu Prompt Energy Spectra in NEOS-II
Authors: Kim Jinyu 
Published: February 2022

Abstract
The NEOS searches for sterile neutrinos by detecting reactor antineutrinos at a very short baseline in Korea. The NEOS detector (1-ton Gd-LS) is deployed at the tendon gallery of the Hanbit reactor unit 5 (2.8 GW thermal power), 23.7 m away from the reactor core. In NEOS-I, we measured the prompt energy spectrum from inverse beta decay using 180 days of reactor-on data and observed the “5 MeV excess”. To understand the origin of the “5 MeV excess”, NEOS-II has taken 368 (120) days of reactor-on (-off) data from September 2018 to October 2020, covering a whole burnup cycle of the reactor. We tested a method for the extraction of the prompt energy spectra for 235U and 239Pu from the whole burnup cycle using pseudo data.
