Light Vector Dark Matter via a Magnetic Dipole Portal: Bridging Direct Detection and Fixed-Target Searches

This paper proposes a sub-GeV vector dark matter model mediated by a non-Abelian magnetic dipole portal that naturally yields an inverse mass hierarchy, demonstrating that a significant parameter space consistent with thermal relic abundance and current constraints can be effectively probed by combining fixed-target experiments with direct detection and cosmological observations.

Searching for Ultralight Dark Matter with MOLeQuTE: a Massive Optically Levitated Quantum Tabletop Experiment

This paper proposes and analyzes a new massive, optically levitated quantum sensor (MOLeQuTE) designed to detect feeble oscillatory forces from ultralight dark matter, demonstrating its potential to operate at the standard quantum limit and significantly advance existing sensitivity limits for vector B-L dark matter.

Freeze-in Production of Non-Abelian Millicharged Vector Dark Matter

This paper presents the first predictive model of vector freeze-in dark matter arising from a hidden non-Abelian SU(2)SU(2) sector broken to a residual U(1)U(1), where massive dark vectors acquire millicharges via kinetic mixing and achieve the observed relic abundance through a two-temperature Boltzmann evolution involving plasmon decay, offering a testable framework for sub-GeV direct detection.

Baryogenesis from the Thermodynamic Arrow of Time: a Transfer-Function Bound and an Entropy-Clock Mechanism

This paper proposes a baryogenesis mechanism driven by an "entropy-clock" chemical potential during reheating, establishing a transfer-function bound that demonstrates successful freeze-out requires the entropy production timescale to overlap with the charge-violation scale, thereby constraining the reheating temperature to be comparable to the freeze-out temperature.

Low-energy scattering of the J/ψπJ/ψπ and J/ψKJ/ψK system

Using a dispersion relation framework that accounts for chiral symmetry breaking and field mixing, this study calculates the low-energy scattering parameters for J/ψπJ/\psi\pi and J/ψKJ/\psi K systems, revealing attractive interactions dominated by soft-gluon exchange with the kaon channel showing moderate enhancement over the pion channel.
