By applying the Gaussian Expansion Method to the Silvestre-Brac potential within a diquark model, this study reveals that centrifugal forces acting on light degrees of freedom invert the expected mass hierarchy in doubly-heavy tetraquarks, a robust mechanism confirmed across various heavy-hadron systems.
This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed corrections to the vector coupling to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
This paper introduces a new parton-shower algorithm that exactly reproduces the dynamics of linearized effective kinetic theory to provide a first-principles description of jet thermalization in QCD plasmas, overcoming previous limitations by properly incorporating recoils, holes, quantum statistics, and merging processes.
This paper investigates the spatial distributions of energy density, pressure, and shear forces within a two-flavor Skyrme model including vector mesons, revealing that the energy-momentum tensor's pseudo-gauge dependence—arising from nonvanishing surface terms of spin currents—causes significant differences between canonical and Belinfante forms, including singularities in the canonical pressure and shear-force distributions at the nucleon center.
This paper demonstrates that kinematic power corrections in deeply virtual Compton scattering dispersion relations provide a novel experimental constraint on nucleon momentum, pressure, and total angular momentum distributions, with continuum and lattice-QCD predictions indicating that momentum distributions account for approximately one-third of the signal at .
This paper demonstrates that including twist-four kinematic power corrections modifies the subtracted constants in deeply virtual Compton scattering dispersion relations, causing the helicity-conserving amplitude to depend on double distributions in addition to the -term, a mixing effect that significantly impacts the extraction of pressure forces from Jefferson Lab data.
This paper utilizes a hybrid theoretical model combining equivalent photon approximations, GiBUU pre-equilibrium dynamics, and statistical decay frameworks to analyze new ALICE ultraperipheral collision data, successfully explaining proton and neutron emission patterns in photon-induced nuclear processes, particularly the near-maximal cross-section for single-proton emission and the high-energy tail of neutron distributions.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper investigates the impact of strongly-interacting dark matter, modeled by a first-principles QCD-like gauge theory, on neutron star structure and confirms that such dark matter can be accommodated within current observational constraints.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
Using lattice gauge theory techniques, this study analyzes the spectral properties of SU(3) gauge theory via overlap Dirac eigenvalues to reveal fractal-like clustering near the chiral crossover and estimate a thermalization time of approximately 1.44 fm/c by linking non-equilibrium chaotic momentum modes to thermal magnetic scales.
This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.
This study utilizes Light-Front Holographic QCD and gauge/string duality to establish a unified framework for extracting quark and gluon distributions and form factors, while demonstrating that the trace anomaly contributes approximately 23% to the proton mass through the analysis of near-threshold production.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.
This study demonstrates that the charge-weak form factor difference in Ca and Zr is highly sensitive to the isovector spin-orbit interaction due to specific shell structures, whereas Pb and Ni remain insensitive, thereby guiding a strategic approach to use parity-violating electron scattering on these distinct nuclei to separately constrain the isovector spin-orbit strength and the symmetry energy slope.
This paper presents predictions for the scattering observables and femtoscopic correlation functions of the and systems within two theoretical frameworks constrained by heavy-flavor resonances, revealing that while strong-interaction models exhibit significant differences, the inclusion of repulsive Coulomb effects largely suppresses the sensitivity of correlation functions to these underlying strong dynamics.
This paper demonstrates that the Serreau–Tissier replica sector in Yang–Mills theories can dynamically generate a Gribov–Zwanziger-type horizon functional through the expansion of the Faddeev–Popov determinant, thereby providing a microscopic mechanism for the emergence of the Gribov scale that yields either a Curci–Ferrari mass or a refined Gribov–Zwanziger decoupling propagator depending on the replica symmetry phase.
This paper investigates how the Weinberg angle, a fundamental parameter in the Standard Model that may vary with environmental conditions, influences the Fermi coupling constant and consequently determines the initial neutron abundance in Big-Bang nucleosynthesis and the neutron lifetime.
