This paper presents an updated analysis of the decay angular distribution incorporating transverse beam polarization, confirming a slope parameter while identifying small but non-negligible two-photon interference effects and predicting a significant azimuthal modulation that motivates future two-dimensional angular studies.
This paper validates a modified Teukolsky framework for predicting gravitational-wave ringdown spectra in effective field theories by successfully passing two rigorous null tests and confirming consistency between two independent numerical methods, thereby establishing its reliability for future strong-field tests of General Relativity.
This study demonstrates that while Monte Carlo neutrino transport in neutron star mergers confirms thermalization in hot, dense regions, significant non-equilibrium deviations in moderately warm zones reveal that energy-averaged agreement with thermal assumptions is insufficient for accurately predicting weak interaction rates and composition evolution.
This paper demonstrates that incorporating Urca processes involving parity partners of nucleons and hyperons within a parity doublet model significantly improves the agreement between neutron star cooling simulations and observed surface temperatures and ages.
This paper presents the first sub-percent precision lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment, yielding a result of that is twice as precise as the 2025 White Paper estimate and shows a significant 4.8 tension with data-driven evaluations excluding the CMD-3 measurement.
This paper extends a single-flavon -lattice Froggatt-Nielsen framework to the lepton sector, successfully generating charged-lepton mass hierarchies and a normal-ordered neutrino spectrum while predicting a distinct two-branch correlation between the atmospheric mixing angle and the CP-violating phase , with a lower-octant solution (, ) favored by theoretical priors.
This paper introduces a nonperturbative Hamiltonian framework that rigorously connects finite-volume lattice QCD spectra to experimental scattering observables, successfully demonstrating its utility by extracting robust resonance parameters for the meson through a unified analysis of coupled and systems.
This paper proposes an extended left-right symmetric model incorporating an additional gauge symmetry and vector-like fermions to explain neutrino mass hierarchies through distinct seesaw mechanisms, while utilizing LHC Run II data to establish lower mass limits on the new and gauge bosons based on their decay channels.
This paper investigates a generalized gauged -Maxwell theory where integrating out a massive Dirac fermion induces a non-polynomial, logarithmic magnetic permeability, enabling the derivation of BPS vortex solutions with quantized magnetic flux that highlight the interplay between target-space geometry and the induced permeability.
This paper presents a physics-informed neural network approach to extract a universal small- dipole scattering amplitude directly from global DIS and photoproduction data without rigid parametric assumptions, successfully resolving the long-standing tension between total and charm cross-section channels while providing a smooth, non-negative input for Color Glass Condensate phenomenology.
