This paper presents a numerical program that calculates deep inelastic scattering structure functions at next-to-leading order accuracy within the dipole picture, utilizing a reformulated expression for massive quark impact factors to ensure stable cross-section evaluations.
This paper investigates the solar production of symmetrons via photon conversion in the tachocline and their subsequent absorption in underground liquid xenon detectors, establishing new astrophysical bounds based on solar luminosity limits and deriving complementary direct-detection constraints using XENONnT data to probe previously uncharted regions of symmetron parameter space.
This paper presents a general prescription for spurion analysis that systematically tracks coupling constants in particle scattering processes governed by commutative non-invertible fusion algebras, unifying previous approaches and supporting the view that such non-invertible selection rules can be described by lifted Abelian groups with explicit breaking terms.
This paper investigates the production of light dark radiation particles (such as dark Higgs scalars, dark photons, right-handed neutrinos, and axion-like particles) via gravity-mediated interactions in the early universe, deriving constraints on the reheating temperature and equation of state from Planck 2018 CMB data and identifying future experimental prospects for probing these scenarios.
This study utilizes galaxy cluster number counts from the SRG/eROSITA all-sky survey, combined with weak lensing data, to establish the first constraints on the relic density of ultralight axion dark matter across a broad mass range, identifying tight exclusion limits in the intermediate mass regime that are further strengthened when combined with cosmic microwave background observations.
This paper proposes a new, gauge-symmetry-compatible formulation for CP-violating neutral triple gauge couplings within the SMEFT framework and demonstrates that future high-energy colliders, particularly with polarized beams, can probe new physics scales ranging from TeV to 10 TeV with sensitivities improving from to as collision energy increases from 250 GeV to 5 TeV.
This paper demonstrates that the observed $CP$ violation in decays implies a penguin amplitude significantly larger than Standard Model predictions and cannot be explained by rescattering alone, thereby providing strong model-independent evidence for physics beyond the Standard Model.
This paper investigates the sensitivity of future high-energy colliders to dimension-8 neutral triple gauge couplings in $ZZ$ production, demonstrating that machine learning techniques applied to angular distributions and beam polarization can significantly enhance the discovery potential for new physics scales up to the multi-TeV range.
This paper utilizes the density of states method in lattice field theory to characterize the first-order confinement/deconfinement phase transition in finite-temperature $Sp(4)$ Yang-Mills theory, demonstrating the persistence of non-perturbative phenomena and establishing critical parameters for future continuum limit extrapolations relevant to gravitational wave predictions.
This paper proposes a novel axion detection method for masses between and eV that utilizes a large cylindrical sample with low electrical conductivity to generate a measurable bulk oscillating current under a magnetic field, offering a feasible signal-to-noise ratio even at cryogenic temperatures.
