Summary: The study shows a connection between the parameters of transient CP violating phase in leptogenesis and the observation of electron electric dipole moment, with the left right symmetric supersymmetric model providing an effective method to connect these parameters. The research results indicate strict constraints on the scale of U(1)(B-L) symmetry breaking and the scale of SU(2)(R) symmetry breaking.

Summary: In multi-component scalar dark matter scenarios, a single Z(N) symmetry is studied for the stability of different dark matter particles, with two species contributing to the observed dark matter density. The analysis of three scenarios shows that new interactions allowed by the Z(2n) symmetry can satisfy current experimental constraints over a wider range of dark matter masses and may lead to observable signals in direct detection experiments. These scenarios can serve as prototypes for other two-component Z(2n) models with one complex and one real dark matter particle.

Summary: Hybrid Inflation is a well-motivated mechanism for cosmic inflation, but faces hierarchy problems; by introducing a discrete twin symmetry, these issues can be addressed, leading to a natural model of non-supersymmetric low-scale inflation.

Summary: This study extends the framework of modular invariant supersymmetric theories to encompass more general discrete groups Γ, involving multiple moduli and connection with the theory of automorphic forms. By constructing a minimal Kahler potential and a general superpotential, the theory can be applied to rigid and local N = 1 supersymmetric theories. Specializing the construction to the case G = Sp(2g, ), K = U(g) and Gamma = Sp(2g, Z), the study shows how the theory can be consistently restricted to multi-dimensional regions of the moduli space with residual symmetries.

Summary: This study provides an extensive analysis of gravitational waves (GWs) generated by global cosmic strings, taking into account recent developments and uncertainties in the models. The results suggest that the frequency spectrum of GW background from global cosmic strings can be used to probe the cosmic history prior to the Big Bang nucleosynthesis.

Summary: The study investigates the IR limits of pure two-dimensional supersymmetric gauge theories with semisimple non-simply-connected gauge groups for various discrete theta angles. It was found that supersymmetry is broken in the IR for most discrete theta angles, except for one distinguished value where it remains unbroken with as many twisted chiral multiplet degrees of freedom in the IR as the rank. The technology of nonabelian mirrors was further developed to discuss the differences between mirrors of G gauge theory and G/K gauge theory.

Summary: The model explores the connection between Dark Matter and neutrinos by introducing new electroweakly charged states and imposing a discrete symmetry, generating a stable Dark Matter candidate. Numerical analysis shows that the model can reproduce neutrino masses, correct dark matter density, and viable dark matter masses. Direct and indirect detection signatures are explored, showing promising detection prospects with CTA, Darwin, and KM3Net, highlighting the complementarity between these observables.

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 investigates symmetry breaking and topological defects in a supersymmetric model with gauge group U(2), which predicts the formation of either monopoles and strings or dumbbells during two phases of hybrid inflation terminated by tachyonic preheating. In one case, a stochastic gravitational wave background generated by a metastable cosmic string network is predicted in the LIGO-Virgo band, extending possibly to the LISA frequency band and to nanohertz frequencies, while in the other case, no topological defects survive inflation and no stochastic gravitational wave background is produced.

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: This study investigates the potential presence of generalized global symmetries in large classes of Type IIB four-dimensional N = 2 effective field theories, and explores how they are avoided. The research finds that the presence of generalized theta-terms plays an important role in breaking a large subset of the global symmetries, while the spectrum of charged states is constituted by an infinitely populated lattice due to the presence of these terms.

Summary: The excess of electron recoil events observed in the XENON1T experiment has been proposed to potentially indicate axion-like particles (ALPs) originated from the Sun or dark matter halo, or due to trace amounts of tritium in the experiment. Combining XENON1T data with astrophysical probes supports the dark matter ALP hypothesis, despite the need for tuning unknown parameters. Bayesian analysis does not show strong preference for the ALP interpretation of the XENON1T excess over the background hypothesis, despite the tensions in the case of solar ALPs.

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 describes the higher-form and non-invertible symmetries of 4d N = 3 S-folds using the brane dynamics of their holographic duals. In cases with enhancement to N = 4 supersymmetry, the analysis reproduces known field theory results and is compatible with the effective action given by Bergman and Hirano. For two specific N = 3 theories, the results agree with those implied by the Lagrangian description. In all other cases, the results provide novel predictions about the symmetries of the corresponding N = 3 field theories.

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: 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: 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.
