Using an improved string-melting AMPT model and novel scaling observables across various collision systems at ~GeV, this study disentangles the initial-state driving and viscous damping effects on directed flow, identifying a collective behavior threshold at mass number and determining a shear viscosity to entropy density ratio () between 0.10 and 0.20.
This paper quantifies how Next-to-Leading Order nucleation calculations and gradient expansion corrections in a classically conformal Abelian Higgs model alter the particle physics interpretation of PTA gravitational-wave signals, revealing that these theoretical refinements significantly shift the preferred gauge coupling and input scale while identifying gravitational-wave spectra uncertainties as the dominant remaining theoretical limitation.
This paper investigates superluminal Lorentz invariance violation in cosmogenic neutrinos using the KM3-230213A event as a benchmark, demonstrating that while current statistics preclude formal constraints, the model predicts a distinct spectral sensitivity to LIV coefficients between and that depends critically on cosmic-ray source properties.
This review outlines modern strategies utilizing dispersion relations, lattice gauge theory, and nuclear many-body calculations to reduce hadronic and nuclear uncertainties in radiative corrections for low-energy weak interaction processes, thereby enhancing the precision of searches for physics beyond the Standard Model.
This paper presents a systematic classification and Bayesian analysis of economical modular lepton-flavor models without right-handed neutrinos or extra flavons, identifying 18 viable normal-ordering and 19 inverted-ordering scenarios that successfully fit current neutrino data while offering distinct, testable predictions for absolute neutrino mass scales and CP-violating phases.
This paper derives a Wandzura-Wilczek-like relation and a Burkhardt-Cottingham-like sum rule connecting the twist-2 and twist-3 tensor-polarized partonic structures of the spin-1 deuteron, and uses HERMES data to phenomenologically estimate that the twist-3 distribution is comparable in magnitude and shape to the twist-2 distribution , suggesting significant subleading-twist effects for future low- experiments.
This paper demonstrates that thermal leptogenesis can successfully generate the observed baryon asymmetry in predictive type-I seesaw models where the neutrino Dirac mass matrix is linked to up-type quarks, down-type quarks, or charged leptons, specifically requiring normal mass ordering, non-zero Majorana phases, and a close-mass pair of heavy neutrinos, while yielding testable predictions for next-generation neutrinoless double beta decay experiments.
This study employs a nonrelativistic quark-antiquark potential model with a Cornell potential and Gaussian spin-spin interaction to successfully reproduce the masses and spectroscopic properties of and mesons, extract consistent HQET couplings, identify specific Regge trajectory assignments for high-mass states, and provide evidence suggesting the exotic nature of the meson.
This paper presents next-to-leading order perturbative QCD predictions for exclusive heavy-quarkonium electroproduction at HERA to establish benchmarks for future Electron-Ion Collider measurements, while advocating for a dedicated resummation framework to address challenges at large photon virtualities.
This paper presents a systematic numerical analysis of a thermal first-order phase transition described by a specific effective potential, mapping its phase structure to a dense atlas of gravitational-wave signals while clarifying the distinction between phenomenological parameter scans and predictive first-principles calculations.
