This paper proposes a scalable, integrated photonics-based experimental approach using refractive index-modulated resonators coupled to single-photon detectors to search for sub-eV dark matter candidates, such as axion-like particles and dark photons, by leveraging nanophotonic confinement to explore previously uncharted parameter space.
This paper analyzes systematic errors arising from higher-twist contamination and kinematic effects in extracting the leading-twist structure function from inclusive DIS on a tensor-polarized deuteron, comparing two target polarization directions to determine that while both options yield comparable errors at Jefferson Lab 12 GeV kinematics, the momentum transfer direction is preferred at higher values.
This paper introduces a new algorithm for the efficient integration-by-parts (IBP) reduction of complex Feynman integrals with high powers of numerators or propagators, utilizing syzygy-constrained symbolic rules and small linear systems to achieve significantly faster computation speeds in demanding applications like multi-loop scattering amplitudes and spinning black hole binary systems.
This paper proposes that cosmological tensions regarding the expansion history and CMB lensing can be resolved by interpreting them as evidence for a negative neutrino mass, which can be realized through new light fields or dark sector models that predict distinct observable signals in polarization and galaxy statistics.
This paper demonstrates that incorporating higher-order curvature corrections (such as and ) into the Starobinsky inflationary model resolves its mild tension with recent P-ACT-LB-BK18 data while imposing new constraints on post-inflationary dynamics.
This paper demonstrates that a lightweight and scalable EfficientNet architecture, augmented with global jet features, achieves competitive top-quark jet tagging performance while significantly reducing computational costs compared to Transformer-based and standard Graph Neural Network approaches.
This paper demonstrates that incorporating two-loop corrections and approximate heavy quark mass effects into the perturbative splitting kernels significantly improves the quantitative accuracy and predictive stability of double parton distributions at small inter-parton distances.
This paper employs renormalizable two- and three-flavor quark-meson-diquark models to analyze color superconductivity and pion condensation in dense quark matter, demonstrating that BCS gaps approach a constant and the speed of sound converges to the conformal limit at high chemical potentials while correctly accounting for global symmetry breaking and Goldstone boson counting.
This study investigates temperature-dependent dark matter-neutrino interactions induced by a dimension-six operator, deriving a full Boltzmann hierarchy that reveals dark acoustic oscillations and establishes significantly tighter cosmological constraints on the interaction strength compared to temperature-independent models, while highlighting the critical impact of realistic neutrino mass ordering on these limits.
This paper demonstrates that a significantly enhanced isovector nuclear spin-orbit interaction, inferred from CREX experimental data on Ca, resolves the PREX-CREX puzzle and explains the emergence of new magic numbers in neutron-rich nuclei while preserving the successful description of standard nuclear properties.
