Summary: Sterile neutrinos that mix with active neutrinos are considered as interesting dark matter candidates, with their production being constrained by structure formation observations and X-ray searches. Resonant oscillations between active and sterile neutrinos can occur in the early universe if active neutrinos couple to an oscillating condensate of a very light gauge field, allowing sterile neutrinos to potentially make up all of the dark matter while respecting X-ray constraints. These deviations from standard neutrino oscillations could still be present today.

Summary: The self-interacting neutrino hypothesis provides motivation for addressing the tension between the origin of sterile neutrino dark matter and indirect detection constraints, and can produce a variety of testable signals from laboratories to the cosmos. In certain models, there must be a lower bound on the amount of extra radiation in the early Universe, which will be further strengthened with an improved x-ray search at the Athena observatory. This intimate relationship will be unambiguously tested by the upcoming CMB Stage 4 project.

Summary: Extending the standard model with three right-handed neutrinos and a simple QCD axion sector can account for various phenomena, but in this model, dark matter does not originate from primordial black holes, but rather consists of a multi-component axion-sterile neutrino composition.

Summary: IceCube has observed a flux of cosmic neutrinos, with a bump in the energy range 10 less than or similar to E/TeV less than or similar to 100, creating tension with gamma-ray data from the Fermi satellite. This tension is interpreted as evidence for hidden cosmic-ray accelerators. The study proposes an alternative explanation based on cold dark matter and sterile neutrinos.

Summary: No significant signals were observed above the expected background, but the study presented the first direct detection limits for a vector interaction in the mass range of 35 to 55 keV/c2, which are the strongest in this mass range compared to other astrophysical and cosmological constraints. The data also provide competitive sensitivity in comparison to existing astrophysical bounds.

Summary: In this study, we propose a Majoron-like extension of the Standard Model where neutrino masses are generated through an inverse seesaw mechanism. We explore the case of Majorana fermions as dark matter candidates in this framework. Additionally, we provide parameter space regions that satisfy current experimental constraints.

Summary: By revisiting the physics and uncertainty of N-1, we find that it is not suitable as a dark matter candidate. The most promising opportunity for detection is to find a line of velocity dispersion similar to 500 km s(-1) in the Virgo cluster with XRISM, and further investigate whether the line is from dark matter in general, and if so, whether it is indeed N-1.

Summary: This study assesses the impact of early Universe pre-BBN cosmology on the mixing range of keV-mass sterile neutrino dark matter, and finds that the uncertainties in early Universe cosmology significantly expand the allowed parameter space for sterile neutrinos that can constitute the whole of the dark matter.

Summary: We studied a light thermal scalar dark matter model and found two parameter regions that escaped the traditional observational constraints. In these regions, higher partial waves dominate the annihilation process, leading to weaker constraints from cosmological observations. We quantitatively considered typical cases of mixing angle and new particle mass and discussed the testability of this model in future experiments.

Summary: The type-I seesaw mechanism can accommodate one of the right handed neutrinos as freeze-in dark matter, with the smallness of the coupling connected to the lightness of the active neutrino mass. This nonthermal production of dark matter has mass.

Summary: The ultralight boson is a potential dark matter candidate with unique wave-like behaviors. We propose a method to detect ultralight dark matter using dark mediators in collider and beam dump experiments, distinguishing it from conventional methods. The time-varying nature of dark mediator mass reduces traditional constraints and enhances sensitivity compared to the time-blind method, also proving effective in detecting invisible decay.

Summary: We study the impact of weakly coupled and light dark photons on the dynamics of neutrino flavor conversions. By analyzing data from T2K, SNO, and Super-Kamiokande experiments, we provide world-leading limits on the dark photon gauge coupling for masses below 10^-11 eV. The degeneracies between shifts in neutrino mass-squared differences, mixing angles, and the new physics effect relax the current constraints on neutrino vacuum oscillation parameters.

Summary: We propose a new mechanism for generating undetectable sterile neutrinos vs in the early Universe, through the conversion of ordinary neutrinos va in scattering processes vsva -> vsvs. This leads to an exponential growth in the abundance of vs after initial production by oscillations. We demonstrate that this production regime occurs naturally for self-interacting vs, offering significant opportunities for vs to account for all observed dark matter. Our findings provide strong motivation to enhance the sensitivity of X-ray line searches and improve constraints from structure formation.

Summary: This study explores the neutrinoless double beta decay induced by an ultralight dark matter field coupled to neutrinos. The coupling violates lepton number and directly drives the AL=2 transition without suppressing small neutrino masses. However, this coupling is likely to alter the standard cosmological results in the early Universe, and the parameter space is severely constrained, making it difficult for future experiments to detect any signal even with a meV sensitivity to the effective neutrino mass.

Summary: ULYSSES is a Python package that calculates baryon asymmetry in the context of leptogenesis. The new version includes solving of Boltzmann equations, including low-scale leptogenesis and primordial black hole-induced leptogenesis. It also provides a script for parameter space scan. The emphasis is on user flexibility and rapid evaluation.

Summary: Sterile neutrinos at the GeV scale have crucial implications for the Standard Model, addressing issues such as the origin of neutrino masses and the baryon asymmetry. However, their small couplings to SM particles make them challenging to detect experimentally. In this study, we investigate the impact of novel interactions involving sterile neutrinos on freeze-in leptogenesis. The results indicate that these interactions can significantly reduce the generated asymmetry by bringing the sterile neutrinos into equilibrium at early times. Additionally, observable rates of certain hidden-sector neutrino signatures may contradict the observed baryon asymmetry, providing an opportunity to falsify freeze-in leptogenesis.

Summary: We study the cosmology and phenomenology of freeze-in baryogenesis via dark-matter oscillations, taking the dark matter to couple to Standard Model leptons. We investigate viable models both with and without a Z(2) symmetry under which all new fields are charged. Lepton flavor effects are important for leptogenesis in these models, and we identify scenarios in which the baryon asymmetry is parametrically distinct from and enhanced relative to leptogenesis from sterile neutrino oscillations. The models we study predict the existence of new, electroweak-charged fields, and can be tested by a combination of collider searches, structure-formation studies, x-ray observations, and terrestrial low-energy tests.

Summary: The proposed program focuses on inclusive, multi-track displaced vertex searches at B-factories, which are expected to have low background and high sensitivity to non-minimal hidden sectors. By studying different production modes of long-lived particles (LLPs) and their possible decays, the study shows that inclusive searches can reveal a wide range of hidden sector models that are currently unconstrained.
