Summary: We propose a novel approach for dark matter search in the DarkSide-50 experiment using Bayesian Networks. Our approach incorporates the detector response model into the likelihood function, without assuming linearity or specific probability distribution functions. By expressing the problem in terms of Bayesian Networks, we have developed an inference algorithm based on a Markov Chain Monte Carlo method. Our approach not only provides information on the parameter of interest, but also allows for studying systematic variations of parameters on the final results.

Summary: This paper reports various searches for weakly interacting massive particle (WIMP) dark matter using the full data set of the XMASS-I detector. The study found limits on the WIMP-nucleon scattering cross section by analyzing the detector's fiducial volume. Additionally, a search for annual modulation signatures in the detector's whole target volume was conducted, and corresponding cross section limits were obtained.

Summary: With the advancement of low-threshold dark matter detectors, the recoil from solar neutrinos can be detected, providing an opportunity to explore neutrino properties. We predict an enhanced event rate of solar neutrino scattering in low-threshold DM detectors beyond the Standard Model interactions, focusing on specific detectors. By considering various neutrino interactions, we place constraints on the mass and couplings of each mediator and the neutrino magnetic moment using both current detectors and future projections. Our findings show significant improvements in constraints for vector and scalar mediators using low-threshold detectors.

Summary: We conducted a search for solar bosonic dark matter using the annual modulation method with the COSINE-100 experiment. However, no modulation signal compatible with the expected models was found. Upper limits were set for each of the three models studied. The future COSINE-200 experiment with NaI(Tl) crystals is expected to improve the sensitivity of the analysis.

Summary: Knowledge of the ionization and scintillation responses of liquid xenon (LXe) to nuclear recoils is crucial for LXe-based dark matter experiments. Current calibrations carry large uncertainties in the low-energy region below similar to 3 keV(nr) where signals from dark matter particles of < 10 GeV/c(2) masses are expected. In this paper, a method to quantify the uncertainties of low-energy LXe responses using published calibration data is described, followed by case studies to evaluate the impact of yield uncertainties on B-8 searches and low-mass dark matter sensitivity in a typical ton-scale LXe experiment. We conclude that naively omitting yield uncertainties leads to overly optimistic limits by a factor of similar to 2 for a 6 GeV weakly interacting massive particle mass. Future nuclear recoil light yield calibrations could allow experiments to recover this sensitivity and also improve the accuracy of solar B-8 flux measurements.

Summary: A decaying cold dark matter model is proposed to explain the excess of electron recoil observed at the XENON1T experiment. The model suggests that daughter dark matter from parent dark matter decay can saturate the peak of electron recoil energy. The proposed model is consistent with experimental limits from dark matter detections, Cosmic microwave background, and large scale structure experiments.

Summary: The study suggests that if dark matter is made up of new fundamental particles, Earth's orbital motion around the Sun may induce an annual modulation in the rate at which dark matter particles interact in a terrestrial detector. The DAMA collaboration observed such an annual modulation in their event rate, but the hypothesis of plasma dark matter as an explanation was rejected at a confidence level greater than 7σ through a chi-squared goodness-of-fit test.

Summary: The diurnal modulation of event rate on solid targets due to directionally dependent defect creation threshold energy can enhance the detection sensitivity for dark matter signals. Using information from both annual and diurnal modulations may provide a similar gain in experiment reach, especially for light dark matter just above the detection threshold.

Summary: We report the search for electron antineutrinos from astrophysical sources using the KamLAND detector. Although some candidate events were observed, no significant excess over the background model was found. Upper flux limits and limits on the annihilation rates for light dark matter pairs were determined. The study also improves the upper probability limit of B-8 solar neutrinos converting into electron antineutrinos.

Summary: We conducted a search for cosmic-ray boosted dark matter using protons as the signal detector, based on the data collected from the Super-Kamiokande experiment during the 1996-2018 period. We specifically focused on the proton recoils near the Galactic Center, aiming to identify any excess above the atmospheric neutrino background. However, no such excess was observed. As a result, we established the most rigorous limits on cosmic-ray boosted dark matter, ruling out the dark matter-nucleon elastic scattering cross section between 10(-33) cm(2) and 10(-27) cm(2) for dark matter mass ranging from 1 MeV/c(2) to 300 MeV/c(2).

Summary: We report the first search for the flux of astrophysical electron antineutrinos in the gadolinium-loaded Super-Kamiokande (SK) detector. By introducing gadolinium into the ultrapure water, the new experimental phase SK-Gd allows efficient background rejection and search for electron antineutrinos via inverse beta decay. The results, based on exposure from August 26, 2020 to June 1, 2022 with 22.5 x 552 kton center dot day at 0.01% Gd mass concentration, show no significant excess over the expected background in the observed events for neutrino energies below 31.3 MeV, placing flux upper limits at the 90% confidence level. The limits and sensitivities are already comparable to previous results with pure water, thanks to the enhanced neutron tagging. Operation with Gd increased to 0.03% started in June 2022.

Summary: This article provides details on a quenching incident of an 18 T high-temperature superconducting (HTS) magnet that occurred in December 2020. The no-insulation (NI) design of the HTS magnet is relatively safe in quenching, but it cannot completely prevent quenching and damage to the associated system. Due to significant vibrations and fast energy dissipation, the magnet and detector components are significantly damaged during quenching. The magnet was inspected and repaired by the manufacturer in spring 2021, and it showed stable and consistent performance after the repair. It is evident that the NI-HTS magnet still requires quench protection circuits to secure the magnet and associated system.

Summary: This paper reports various searches for weakly interacting massive particle (WIMP) dark matter using the full data set of the XMASS-I detector. The study found limits on the WIMP-nucleon scattering cross section by analyzing the detector's fiducial volume. Additionally, a search for annual modulation signatures in the detector's whole target volume was conducted, and corresponding cross section limits were obtained.

Summary: This paper investigates the impact of total internal reflection on photon propagation and reconstruction in liquid-scintillator neutrino detectors, and develops a precise detector-response model. By parameterizing the detector response, unbiased energy and vertex reconstruction are achieved, and a criterion is proposed to avoid multimodality in the reconstruction likelihood function.

Summary: We report on the details of an axion dark matter search experiment using high-temperature superconducting magnet and Josephson parametric converter technologies. The experiment involves an 18 T high-temperature superconducting solenoid magnet and utilizes a Josephson parametric converter as a low-noise amplifier. A search for dark matter axions was conducted using the 18 T axion haloscope, but no significant signal consistent with Galactic dark matter axions was observed. The results set the best limit on the axion-photon-photon coupling in the axion mass range of 19.764-19.890 mu eV.

Summary: We use data from the COHERENT CsI[Na] scintillation detector to constrain sub-GeV leptophobic dark matter models. No evidence for dark matter is observed and a limit on the mediator coupling to quarks is placed. COHERENT sets the best constraint on leptophobic dark matter at these masses.

Summary: This article introduces the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory, which is a pulse neutron source and also generates pulse neutrinos as a by-product. The COHERENT collaboration uses this source to study coherent elastic neutrino-nucleus scattering. The article discusses the Geant4 simulation of neutrino production at the SNS and the flux calculation, estimating the uncertainty of the calculation at around 10% based on validation against low-energy pi(+) production data.

Summary: The light yield of a small undoped CsI crystal coupled with SiPMs at cryogenic temperature was measured, showing great potential for neutrino and low-mass dark matter detection. However, the use of cryogenic SiPMs instead of PMTs may have some drawbacks, including worse energy resolution and optical cross-talks.
