Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.
Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.
Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.
This paper presents a next-to-leading order expansion formula for computing parton distribution functions from current-current correlators, which offer simple renormalization properties and avoid linear power divergences, alongside preliminary numerical results utilizing four-point functions on the lattice.
This paper predicts the existence of a lighter scalar partner, , for the recently observed tetraquark based on CMS data, urging further experimental investigation to confirm an S-wave multiplet of states and distinguish between competing theoretical models.
This paper analyzes one-dimensional theory on a lattice to demonstrate that Gaussian models fail primarily due to structured dependencies between Fourier modes rather than marginal non-Gaussianity, leading to the identification of three distinct regimes and a simple diagnostic criterion for determining when more expressive nonlinear models are necessary.
This study presents a lattice QCD calculation of the nucleon's strange electromagnetic form factors, including electric and magnetic radii and the magnetic moment, using twisted-mass fermions at the physical point and multiple lattice spacings to achieve a continuum limit with high-precision stochastic noise mitigation for disconnected contributions.
This paper outlines a strategy to efficiently compute electromagnetic sea-quark effects in QCD+QED by analyzing stochastic estimator variances to improve the precision of challenging disconnected diagrams, supported by preliminary results from domain-wall fermion ensembles.
This article generalizes the dynamical 3-winding number invariant of minimal two-band systems to generic multiband Chern insulators, proves its equivalence to the difference of Chern numbers between post- and pre-quench Hamiltonians, and reveals unique multiple fermion structures in the phase band that are inaccessible in two-band models.
Using Monte Carlo simulations on SU(3) gauge theory lattices, this study investigates topologically stable strings formed at domain wall junctions in the deconfined phase, revealing that their free energy is dominated by the walls and that thermal fluctuations near the transition point cause these structures to decay into confined-deconfined interfaces.
This paper identifies a novel noncompact Lie symmetry, generated by on-site U(1) fermion number and non-on-site Majorana translation, that enforces the existence of Fermi surfaces with at least two noncontractible components in quantum lattice fermion models, thereby realizing a powerful form of symmetry-enforced gaplessness.
This paper provides direct experimental evidence for quark confinement within the proton by demonstrating that the force between quarks is attractive and constant across a wide range of positions, derived from available data and Quantum Chromodynamics.
This paper employs the local operator-product-expansion method to independently derive twist-2 relations, specifically a Wandzura-Wilczek-like relation and a Burkhardt-Cottingham-like sum rule, for the twist-3 tensor-polarized distribution function of spin-1 hadrons, thereby providing a robust theoretical foundation for upcoming electron-deuteron deep inelastic scattering experiments at JLab.
