Summary: In this paper, the interaction between dark matter and the Standard Model is studied, leading to a possible phenomenon of dark magnetic dipole moments. Through the investigation of a simple toy model, it is found that the existence of dark matter can result in outcomes that are compatible with existing experimental constraints and exhibit different characteristics once the DP is discovered. In specific parameter space regions, the invisible decay of DP may be more preferred.

Summary: The study explores a simple extension of the Standard Model by adding two complex singlet scalars with U(1) symmetry. A discrete Z2xZ2' symmetry is imposed in the model, and the generation of gravitational waves from unstable annihilating domain walls and strong first-order phase transition is investigated. Observational signatures from these gravitational waves at future detectors are also discussed.

Summary: The authors present a mechanism of kinematically forbidden dark matter annihilations into Standard Model leptons, which precisely selects the dark matter mass that gives the observed relic abundance. This mechanism differs qualitatively from existing models of thermal dark matter, where fixing the relic density typically leaves open orders of magnitude of viable dark matter masses.

Summary: This paper reviews and analyzes precision measurements in allowed nuclear beta decays and neutron decay, confirming the V-A character of the interaction and updating the values for V-ud and g(A) at the 10^(-4) level. By incorporating data from mirror beta transitions in new global fits, the study also places new stringent limits on exotic couplings involving left-handed and right-handed neutrinos.

Summary: The study precisely calculates the number of relativistic species, N-eff, in the standard model and predicts it will be measured to the percent level by CMB-S4 in the future. Neutral-current non-standard interactions are found to impact neutrino decoupling in the early Universe, subsequently modifying N-eff. The results provide a comprehensive analysis of the dimension-7 parameterized operators in effective field theory framework and offer a stringent constraint on the dimension-6 vector-type neutrino-electron operator's scale.

Summary: This study carefully analyzes the stochastic gravitational wave production from cosmological phase transitions in an expanding universe, considering both radiation and matter dominated histories. The dynamics of the phase transition, including various factors like bubble lifetime distribution and mean bubble separation, are studied in detail. The study also provides insights into the gravitational wave spectrum and highlights the potential of distinguishing between different expansion histories based on features of the gravitational wave spectral form.

Summary: The study demonstrates the potential of realizing warm inflation in a minimal extension of the Standard Model, which can address various shortcomings of the Standard Model. The use of symmetries within the model not only helps to protect the scalar potential against thermal corrections, but also provides a possible explanation for the existence of dark matter.

Summary: This study presents new limits on the cosmic expansion rate and relativistic energy density using the latest observations from Big Bang Nucleosynthesis (BBN) and the cosmic microwave background (CMB). The findings provide important constraints on early dark energy models and reveal the potential for exploring changes in neutrino species and the baryon-to-photon ratio across different cosmic epochs.

Summary: The paper investigates how the Mirror Twin Higgs could be modified to be compatible with current cosmological constraints without explicit Z(2) breaking. It presents two simple models, one that can solve the N-eff problem and bring the abundance of mirror atoms to an allowed level, and another that leads to mirror neutron dark matter.

Summary: This paper systematically derives the SP equations and relativistic corrections from the nonlinear and fully relativistic KGE equations in an expanding universe, providing insights into deviations and applicability beyond the SP system. The method presented simplifies the analysis of scalar dark matter dynamics and accurately captures deviations from the SP system towards the full KGE case, particularly in calculating the mass-radius relationship of solitons.

Summary: The recent excess observed in the electron recoil data of XENON1T can be explained by anomaly-free axion-like particle (ALP) dark matter, which may have played a role in driving inflation in the early universe. The study suggests successful reheating after inflation requires ALP couplings to heavy fermions, followed by an entropy dilution of O(10) achieved through decays of right-handed neutrinos to explain the XENON1T excess.

Summary: In this paper, the non-adiabatic evolution of dark sector is studied in the framework of a U(1)(L mu)-( L tau )circle times U(1)(x) extension of the standard model. The connection between the visible and dark sectors is established through a portal coupling. The temperature evolution and various non-equilibrium stages of the dark sector are analyzed. Constraints on the model parameters from laboratory and astrophysical searches are investigated. The parameter space for the non-adiabatic evolution of the dark sector is significantly constrained for certain values of mass and coupling, while other constraints depend on the mass ratio.

Summary: The mechanism proposed in the article allows for obtaining multiple inflection points for the inflaton potential based on the zeros of the inflaton quartic coupling beta function and a sign change of the gauge coupling beta function. A universal inflaton potential is presented that can accommodate observational data and may be tested by upcoming cosmic microwave background observations.

Summary: Magnetic monopoles and Q-balls are examples of topological and nontopological solitons. A new soliton state called Q-monopole-ball, which has both topological and nontopological charges, has been discovered in a monopole sector. Stable Q-monopole-balls can contain large magnetic charges and may explain the existence of dark matter.

Summary: This paper introduces a strategy that takes into account the presence of kinematic substructure and models the tail of the velocity distribution as a sum of multiple power laws. The robustness of this method is demonstrated using mock data and data from Milky Way simulations. In a companion paper, the new measurement of the escape velocity and the mass of the Milky Way using Gaia eDR3 data is presented.

Summary: Measuring the escape velocity of the Milky Way is crucial for understanding its mass, dark matter velocity distribution, and dark matter density profile. In this study, a strategy is introduced to robustly measure the escape velocity by considering the presence of kinematic substructures. The results show that the escape velocity at the solar position is v(esc) = 445(-8)(+25) km/s, and the Milky Way has a considerably lighter mass than previous measurements when assuming a Navarro-Frenck-White dark matter profile.

Summary: A study finds that inelastic scattering of dark matter off a nucleus can generate electromagnetic signals with GeV-scale energy, which can be directly detected by the IceCube detector. With detailed signal and background simulations, it is discovered that IceCube can probe dark matter masses up to one gram, assuming approximately 1 GeV deposited energy in each interaction.

Summary: DarkELF is a PYTHON package that calculates the interaction rates of light dark matter in dielectric materials, taking into account screening effects. The package parametrizes the full response of the material in terms of the energy loss function (ELF), which is then converted into differential scattering rates for direct dark matter electron scattering and through the Migdal effect. It can also calculate the rate of phonon production from sub-MeV dark matter scattering via the dark photon mediator, as well as the absorption rate for dark matter composed of dark photons.

Summary: Silicon carbide (SiC) is proposed as a novel material for direct detection of sub-GeV dark matter due to its unique properties and tunable sensitivity to various dark matter models. SiC holds much promise as a dark matter detector, combined with its widespread use as an alternative to silicon in other detector technologies.
