Summary: We propose a new method for discriminating sub-micron nuclear recoil tracks from instrumental background in fine-grain nuclear emulsions used in directional dark matter search. The method utilizes a 3D Convolutional Neural Network with parameters optimized by Bayesian search. Unlike previous studies focused on extracting directional information, our study focuses on signal/background separation by exploiting the polarization dependence of the Localised Surface Plasmon Resonance phenomenon. Comparisons with conventional cut-based approaches show a significant improvement in the reduction factor for a given signal efficiency.

Summary: We report the first measurement of radiation from a 178mHf sample for the purpose of searching for dark matter. The gamma flux from the sample was measured using a Ge detector and the obtained limits on this gamma flux were used to constrain the parameter space of inelastic dark matter. Furthermore, we discuss the potential of future studies with 178mHf.

Summary: In this paper, we explore the different phases of a condensed dark matter candidate, which is a fermion with a Yukawa coupling to a scalar particle. We investigate the BCS, BEC, and crossover phases as a function of model parameters and consider emergent effects such as scalar-density condensate and superfluid gaps. By numerically solving the consistent set of gap equations, valid in both the nonrelativistic and relativistic regimes, we discuss the equation of state and possible astrophysical implications for asymmetric dark matter.

Summary: A laboratory technology has been developed for a new ultra-low background hybrid material that meets the requirements for neutron absorption and detection. This material, based on a PMMA polymer matrix with gadolinium nuclei, can be useful for low background underground detectors designed to search for dark matter. The technology includes a method to determine impurity elements in Gd-based preparations and achieve low detection limits for uranium and thorium. Commercial Gd-based preparations showed low U and Th contents, which were either manufactured from secondary raw materials or mineral raw materials.

Summary: This study shows that the nondetection of gravitational waves from low-mass black hole mergers can place constraints on the interactions between nonannihilating dark matter particles and nucleons. With LIGO data, benchmark constraints for different types of dark matter have been determined, which will help detect particle dark matter and test its ability to explain the absence of pulsars in the Galactic center.

Summary: The generic properties of compact objects made of two different fluids of dark matter are studied. Compact objects with a core-shell structure and mixed dark matter components are investigated. The results show novel features in the mass-radius relations for combined dark matter compact objects, distinguishing them from compact objects with a single dark matter fluid and compact stars made of ordinary baryonic matter.

Summary: In this study, a relativistic mean-field hadronic model with the inclusion of dark matter particle and short-range correlations is used to investigate neutron stars. The model successfully reproduces the constraints on mass-radius diagram imposed by various data analyses, and shows the possibility of more massive neutron stars due to the balancing effect of short-range correlations. Additionally, the study explores the impact of uncertainties in bulk parameters related to the hadronic sector on the neutron star mass-radius profiles, and finds compatible solutions with recent astrophysical constraints.

Summary: Recent studies using New Horizons's Long Range Reconnaisance Imager (LORRI) images have provided precise measurements of the cosmic optical background, showing a flux that exceeds expectations by a factor of 2. The study investigates whether this excess is related to the decay of axionlike dark matter into monoenergetic photons.

Summary: In this study, we investigate the influence of dark matter on hybrid star properties. We assume that dark matter interacts with both hadronic and quark matter through the exchange of a Higgs boson. The properties of hybrid stars are obtained using equations of state calculated with a Maxwell prescription. Our results show that dark matter does not affect the phase transition points but changes the discontinuity in energy density, leading to a decrease in the minimum mass star with a quark core. Additionally, dark matter significantly alters the mass-radius diagrams and the location of merger polarizability curves within the confidence lines.

Summary: Interactions with a background medium can modify the dispersion relation and canonical normalization of particles. This is important when considering the coupling between light dark matter and quarks and leptons. In this paper, the authors discuss this issue in the context of a vector dark matter background with randomly distributed polarizations or a fixed polarization in a single direction. The observations related to particle dispersion can impose constraints on new light Abelian gauge boson models. The classical vector field also induces significant changes in particle normalization, ruling out a large parameter region of the generic vector dark matter model.

Summary: We study the mass-radius relation and the second Love number of compact objects made of ordinary matter and non-self-annihilating fermionic dark matter. We find that the second Love numbers of these objects can be significantly different from those of neutron stars without dark matter. Measuring the tidal deformability of these compact objects can determine the presence of dark matter inside neutron stars.

Summary: Comparison is made between dark matter (DM) detection using new nuclear emulsions and minimum ionizing particle (MIP) detection, radiation therapy (RT) using conventional nuclear emulsions, and picture-taking using color films. The behaviors of electrons and positive holes with varying concentrations in 200nm AgBr grains are analyzed to understand the effect on latent image formation. It is predicted that DM detection and RT are disturbed by direct recombination and reaction between Agn and Br2 due to high activity of positive holes, while MIP detection and picture-taking are solely disturbed by indirect recombination. Ideas to enhance latent image formation in the presence of high concentration electron-hole pairs are discussed based on the obtained results.

Summary: This study investigates the properties of exotic stars made entirely of dark matter, considering intrinsic anisotropies that have been ignored so far. Semi-analytical solutions to the structure equations are obtained, showing that these solutions behave well within general relativity and can describe realistic astrophysical configurations. A direct comparison with isotropic counterparts with the same radius reveals that the latter are slightly more massive.

Summary: Low-temperature calorimeters based on Transition Edge Sensors (TESs) are suitable for rare event searches. The novel design of the thermometer coupling, called remoTES, extends the applicability of the TES technology to a wider range of potential absorber materials, including hygroscopic and low melting point materials. Experimental results show that remoTES calorimeters achieve high energy resolution for both silicon and alpha-TeO2 absorbers. The simplified production process and higher reproducibility make remoTES calorimeters more desirable for large detector arrays.

Summary: This paper presents a novel method for identifying low-energy (less than 30 GeV) νe using an improved emulsion film scanning system. The method is expected to increase the detection efficiency of νe in the low-energy region by 25-70%, leading to enhanced sensitivity of OPERA to neutrino oscillations in the 3 + 1 model. By applying this method to a subset of data, one additional νe candidate is identified. The combined analysis with the appearance of ντ improves the upper limit on sin^2(2)θμe to 0.016 at 90% C.L. in the Mini-BooNE allowed region Δm^2 ~ 0.3 eV^2.

Summary: CRESST, a leading dark matter experiment, utilized cryogenic bolometers to detect nuclear recoils from the target crystal nuclei of CaWO4 during its second phase. The previously established electromagnetic background model, based on Secular Equilibrium (SE) assumptions, was validated in this study by comparing two likelihood-based normalization results using a Bayesian likelihood approach. Despite the deviations from SE observed in some cases, it was concluded that these deviations were artifacts of the fit and that the assumptions of SE are physically meaningful.

Summary: Models of dynamical wave function collapse describe the breakdown of quantum superposition due to system mass increase by introducing non-linear and stochastic modifications to Schrodinger dynamics. Continuous Spontaneous Localization (CSL) has been extensively studied theoretically and experimentally. Measurable consequences of the collapse phenomenon depend on different combinations of the model parameters (strength λ and correlation length r(C)), leading to exclusion of certain regions in the parameter space (λ - r(C)).

Summary: Modern physics builds on the success of Quantum Mechanics in describing the microscopic world, but open questions about measurement and wave function collapse remain. To explore models beyond standard QM, we conduct experiments at the Italian National Gran Sasso underground Laboratory using radiation detectors. We have excluded the natural parameterless version of the Diosi-Penrose model and set strict bounds on the CSL model. Our VIP-2 experiment aims to detect violations of the Pauli Exclusion Principle in Copper and the VIP-3 experiment upgrade is planned for the near future. We also discuss the VIP-Lead experiment and its importance in constraining non-commutative quantum gravity theories.

Summary: This study presents a directional search for boosted Dark Matter using a module of the NEWSdm experiment. The module consists of Nano Imaging Trackers with nanometric granularity, which allows for a low background. The module is installed on an equatorial telescope and can detect an excess of nuclear recoils induced by boosted Dark Matter pointing towards the Galactic Center. The surface laboratory configuration is the most powerful approach for a directional observation with high sensitivity.

Summary: This study aims to establish strict constraints on a class of non-commutative spacetime scenarios as a universality class for various quantum gravity models. It examines slight violations of the Pauli exclusion principle, as predicted by these models, by searching for Pauli forbidden K-alpha and K-beta transitions in lead. By using a high atomic number target material, the energy scale of spacetime non-commutativity emergence at high atomic transition energies can be tested. As a result, this measurement provides valuable information for setting the first constraint on the triply special relativity model proposed by Kowalski-Glikman and Smolin, with the characteristic energy scale being bound to Lambda > 5.6 . 10 (-9) Planck scales.

Summary: ESSnuSB is a design study aimed at measuring CP violation in the leptonic sector at the second neutrino oscillation maximum using a powerful neutrino beam produced by the ESS linear accelerator. The reduced impact of systematic errors at the second maximum enables a highly precise measurement of the CP violating parameter. This review discusses the advantages of measurements at the second maximum, upgrades to the ESS linac, detector complexes, and the expected physics reach of the proposed ESSnuSB experiment, as well as future developments for project realization.

Summary: In this study, a super-fine-grained nuclear emulsion called nano imaging tracker was used as a neutron detector to measure the sub-MeV energy spectra of environmental neutrons. By upgrading the automated scanning system, the measurement was carried out with sufficient statistics and a flux of (7.6 +/- 1.7) x 10-3 n/(cm2 s) was measured in the proton energy range of 0.25 to 1 MeV, consistent with the prediction.
