Stochastic analysis of finite-temperature effects on cosmological parameters by artificial neural networks

This paper employs artificial neural networks and stochastic optimization to demonstrate that incorporating finite-temperature quantum gravity corrections, represented by new density parameters ΩΛ2\Omega_{\Lambda_2} and ΩΛ3\Omega_{\Lambda_3}, improves the fit to Planck 2018 cosmic microwave background data despite the persistence of the Hubble tension.

Complex Scalar Singlet Model: Electroweak Phase Transition and Gravitational Waves

This paper investigates the Complex Scalar Singlet Model as a framework for electroweak baryogenesis, utilizing machine learning to identify parameter regions that support a strong first-order phase transition and produce stochastic gravitational wave signals detectable by future space-based observatories like LISA and DECIGO.

The N=1{\cal N}=1 supersymmetric Pati-Salam models with extra SU(2)L2/R2SU(2)_{L_2/R_2} gauge symmetry from intersecting D6-branes

This paper presents the first construction of three-family N=1{\cal N}=1 supersymmetric Pati-Salam models with extra SU(2)L2/R2SU(2)_{L_2/R_2} gauge symmetries from intersecting non-rigid D6-branes, demonstrating how adding a dd-stack of branes reduces filler branes and exotic particles while generating useful vector-like states and new model classes.

Detection prospects for heavy WIMP dark matter near supermassive black holes, particularly in M31

This paper evaluates the potential for the Cherenkov Telescope Array (CTA) to detect heavy WIMP dark matter annihilating in density spikes around supermassive black holes, concluding that M31* is a prime target capable of probing a significant portion of the TeV-scale WIMP parameter space, potentially surpassing constraints from the Milky Way's central black hole.

The role of charm and unflavored mesons in prompt atmospheric lepton fluxes

This paper evaluates the impact of intrinsic charm and unflavored meson production on prompt atmospheric muon and neutrino fluxes, revealing tensions between IceCube's high-energy muon measurements and neutrino upper bounds that necessitate refined hadronic interaction models and future experimental data to resolve.

Cosmological stasis and the coupled dark sector of the Dark Dimension

This paper investigates cosmological stasis within coupled dark matter and dark energy models motivated by the Dark Dimension, demonstrating that exact stasis requires specific exponential or integrable running slopes, establishing analytic parameter exclusions independent of initial conditions, and revealing that while future capture into stasis is geometrically excluded under fifth-force constraints, dark matter production from the Standard Model brane enables a distinct stasis epoch not accessible in standard scenarios.
