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 scotogenic model generates Majorana neutrino masses radiatively, with dark matter particles running in the loop. We explore the parameter space in which the relic density of fermionic dark matter is generated via a conversion-driven freeze-out mechanism. The model can also resolve the recently reported deviation in the W-boson mass while satisfying constraints from direct detection, charged lepton flavor violation as well as collider bounds. Parts of the parameter space lead to long-lived particle signatures to be probed at the LHC.

Summary: In this paper, a Portalino-like model of dark matter and neutrino masses is explored, where right-handed neutrino fields connect gauge neutral operators from the Standard Model and Hidden Sector. Neutrino masses are generated through a seesaw-like mechanism that explains the light active neutrino masses. The model includes a Portalino state that connects the two sectors via the neutrino portal. The viable mass ranges for the Portalino states are found to be 0.02 eV ≤ mn ≤ 6.4 eV or 489 MeV ≤ mn ≤ TeV, considering constraints from Big Bang Nucleosynthesis and measurements of the Cosmic Microwave Background radiation.

Summary: Constraints are placed on dark matter sterile neutrino scalar decay production, with results indicating that the mass fraction and mass of the sterile neutrino within the co-moving free-streaming horizon are constrained. The datasets used in the analysis provide sensitivity to these parameters and are in agreement with experimental observations.

Summary: Massive cosmological neutrinos can smooth the large-scale structure in the universe and delay structure formation. N-body simulations involving neutrinos are used to measure the merger and mass accretion history of dark matter halos. It is found that non-zero neutrino masses delay the formation of halos within a certain range of virial mass, while non-zero neutrino asymmetry parameter has the opposite effect. The dependencies of these parameters also evolve with redshift.

Summary: This study analyzes the coupling between ultra-light dark matter (ULDM) and neutrinos, and explores the discovery potential through time variations in neutrino mass and mixing parameters. The sensitivity of future neutrino oscillation experiments to both time-averaged and time-resolved modulations is established. The emphasis is placed on time modulations of CP violating mixing phase. A toy model is used to illustrate the case where the leading modulation effect can be CP violating while the effect on CP conserving parameters is suppressed. The study reveals the unique imprint of time-averaged CP violating modulation of ULDM in neutrino oscillations, while direct CP asymmetries vanish.

Summary: The proposed model, based on the multicritical point principle, explains the electroweak scale, neutrino masses, Dark Matter, and inflation successfully by introducing two singlet scalar fields and heavy Majorana right-handed neutrinos into the Standard Model. By assuming a Z(2) symmetry, one of the scalars becomes a Dark Matter candidate with properties similar to minimal Higgs-portal scalar Dark Matter. The model can naturally achieve a saddle point in the Higgs potential at high energy scales, allowing for successful inflation with specific parameter values.

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: The study revisited the possibility of light-scalar dark matter coupled to electrons through fermion or vector mediators, and established new limits and loop-induced processes strengths. Various constraints were considered, largely excluding the explanation of the International Gamma-Ray Astrophysics Laboratory excess of 511 keV photons by galactic annihilation of these particles.

Summary: We propose a new physics model that extends the Standard Model (SM) by introducing hyperchargeless Y=0 triplet fermions and a Higgs triplet with hypercharge Y=2. This model provides a unified framework for explaining neutrino mass and mixing, dark matter, baryogenesis, inflation, and the reheating temperature of the Universe. The model predicts that the two Z2 even neutral fermions explain neutrino low energy variables, while the third Z2 odd fermion triplet serves as a viable dark matter candidate and the scalar triplet acts as the inflaton. Reheating analysis shows that the triplet fermions associated with the Z2 even sector can explain the observed baryon asymmetry at the TeV scale.

Summary: The axion is a highly motivated elementary particle that could address two fundamental questions in physics- the strong CP problem and the dark matter mystery. Experimental searches for this hypothetical particle have reached theoretically interesting sensitivity levels, particularly in the micro-electron volt (gigahertz) region, and have promising applications. By employing different techniques and advanced technologies, the search range can be expanded and the sensitivity can be improved, enabling a comprehensive exploration of the parameter space for axions and axion-like particles in the coming decades.

Summary: This article reviews the development of the axion as a candidate particle for dark matter. It describes the historical roots of the axion in the Standard Model of particle physics and the problem of charge-parity invariance of the strong nuclear force. It discusses the production of the axion as a dark matter candidate and its interactions with ordinary matter.

Summary: Neutrino emission coinciding with gamma rays has been observed from the blazar TXS 0506 + 056 by the IceCube telescope. These neutrinos had to traverse through a dense spike of dark matter surrounding the central black hole. The observation of such neutrinos implies new upper limits on the neutrino-dark matter scattering cross section as a function of dark matter mass. The constraint is stronger than existing ones for a range of dark matter masses, assuming a linearly rising cross section with energy. Competitive bounds are also possible for constant cross sections, depending on the details of the dark matter spike.

Summary: This study investigates the interaction mechanisms between dark matter and nuclei, providing new analytical calculations and revealing the limitations of previous approximations in predicting scattering cross sections. The analysis shows that form factors can vary significantly within the momentum transfer range, challenging the commonly used approach of considering their value at zero momentum transfer.

Summary: The Dresden-II experiment observed coherent elastic neutrino-nucleus scattering with reactor antineutrinos, expanding research on various beyond the Standard Model scenarios. The study explores constraints on nonstandard interactions, magnetic moments, and models with light scalar or vector mediators, highlighting synergies between spallation neutron source and reactor experiments. Additionally, possible signals from scenarios involving elastic scattering off electrons are investigated, revealing stricter constraints in certain parameter spaces compared to coherent elastic neutrino-nucleus scattering.
