This paper utilizes a three-quark light-front model to calculate the gluon Sivers function of a proton at moderately small and numerically determines its small- evolution via the BFKL anomalous dimension, revealing a power-law tail behavior of at high transverse momentum.
This study utilizes Langevin dynamics within an extended quasiparticle model to demonstrate that while electrical conductivity significantly influences the splitting of directed flow () between D and B mesons via electromagnetic fields at LHC energies, chiral conductivity plays a marginal role, ultimately revealing opposite signs for charm and bottom mesons with the latter exhibiting smaller magnitudes.
This paper presents a self-contained next-to-next-to-leading-order (NNLO) perturbative QCD calculation of dimuon production in neutrino-nucleus deep-inelastic scattering based on the semi-inclusive DIS framework, demonstrating that these corrections significantly reduce scale uncertainties at large momentum fractions and alleviate the tension between dimuon and LHC data at small momentum fractions by introducing negative corrections.
This paper presents a comprehensive formalism and phenomenological analysis for calculating exclusive dijet production in electron-proton collisions using collinear QCD factorization and Generalized Parton Distributions, highlighting distinct kinematic behaviors of valence quark contributions at high that are inaccessible at HERA but promising for future Electron Ion Collider measurements.
This paper demonstrates that simulation-based inference (SBI) is a viable and potentially superior alternative to traditional empirical tuning for determining neutrino interaction model parameters, as it successfully reproduces and slightly improves upon the MicroBooNE collaboration's tuned GENIE configuration while also approximating the NuWro simulation.
This paper provides numerical evidence that the consistency of the 4D effective theory in Kaluza-Klein compactification requires the existence of a light scalar modulus with a mass ratio to the first KK graviton squared of at most 4/3, thereby establishing a universal limit on how rigidly the compact manifold can be stabilized.
This paper establishes a comprehensive Spin Density Matrix framework for analyzing polarization transfer in the decay chain , demonstrating that the state perfectly preserves the initial polarization in the dominant -wave limit while providing a unified method to quantify -wave deviations and extend these insights to other hadronic and electroweak processes.
This paper investigates the energy loss of high-energy partons in anisotropic plasmas within the harmonic approximation, deriving a simple formula for the impact of anisotropy and demonstrating that the resulting medium length dependence exhibits universal limiting attractor characteristics consistent with QCD kinetic theory simulations.
This paper calculates the next-to-eikonal cross section for back-to-back dijet production in deep inelastic scattering at small , demonstrating how these corrections relate to the -dependent phase of twist-2 gluon TMDs and twist-3 unpolarized gluon TMDs.
Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for massless flavors may be described by a conformal manifold of -dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.
