Enhancing Direct Detection of Higgsino Dark Matter

This paper proposes that enhancing direct detection sensitivity for inelastic Higgsino dark matter is achievable by utilizing heavy elements around detectors and accounting for terrestrial radioactivity and the Large Magellanic Cloud's influence on dark matter velocity, potentially allowing experiments like JUNO and SNO+ to cover the remaining supersymmetric parameter space.

Bridging inflation and reheating: chiral gravitational waves from aHz to GHz

This paper investigates chiral gravitational waves generated by a parity-violating term in teleparallel gravity from inflation through reheating, demonstrating how these signals produce distinct CMB correlations detectable by LiteBIRD and enhanced high-frequency amplitudes accessible to future resonant cavity experiments, thereby offering a unique multi-frequency probe of early Universe parity violation.

Probing Purely Inelastic Scalar Dark Matter Across Colliders and Gravitational Wave Observatories

This paper proposes a purely inelastic scalar dark matter model that simultaneously explains the observed relic abundance, predicts detectable gravitational waves from a first-order phase transition, and offers long-lived particle signatures at the HL-LHC, creating a unique multi-messenger scenario for experimental validation.

Cavity Multimodes as an Array for High-Frequency Gravitational Waves

This paper demonstrates that a single microwave cavity operating with a background magnetic field can function as a multi-mode detector array, enabling the localization and reconstruction of high-frequency gravitational wave properties—such as polarization and frequency drift—through the distinct antenna patterns of its nearly degenerate electromagnetic modes, thereby enhancing sensitivity to astrophysical sources.

Gravitational Waves from Primordial Black Holes formed by Null Energy Condition Violation during Inflation

This paper proposes that a transient violation of the null energy condition during inflation generates primordial black holes and a distinctive, multi-component stochastic gravitational wave background—encompassing primordial, scalar-induced, ringdown, and binary merger signals—that can be probed through future multi-band observations to constrain inflationary physics.

Can Primordial Black Holes Be Seeds for Early Galaxies in Models Satisfying the Covariant Entropy Bound?

This paper proposes a cosmological model satisfying the Covariant Entropy Bound where early-universe tiny black holes decay to generate the radiation-dominated era and CMB observations, while a distribution of larger primordial black holes and their Planck-scale remnants account for dark matter and the formation of early galaxies observed by the James Webb Space Telescope.

No Evidence for Superradiant Axions in LIGO-Virgo-KAGRA GWTC-5 Binary Black Hole Spins

Using spin measurements from the LIGO-Virgo-KAGRA GWTC-5 catalog of 257 binary black hole mergers, this study finds no evidence for superradiant axion clouds, thereby excluding axion masses between 1.7×10−141.7 \times 10^{-14} and 3.3×10−123.3 \times 10^{-12} eV at 95% confidence and providing one of the most robust lower bounds on the QCD axion mass to date.

One-loop matching of QCD currents to power-suppressed two-jet operators

This paper presents the first next-to-leading order matching of QCD quark-antiquark currents onto two- and three-particle two-jet operators in soft-collinear effective theory up to second order in the power expansion, demonstrating endpoint factorization to ensure the consistent cancellation of singularities for power corrections in two-jet processes.
