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 introduces homotopy lattice gauge fields (HLGFs), a framework based on higher parallel transport that enriches standard lattice gauge theory with homotopy data to reconstruct principal bundles and compute topological charges without requiring prior knowledge of higher category theory.
This paper presents preliminary lattice results on the vector-channel scattering of two pseudoscalar states in an $Sp(4)$ gauge theory with two fundamental Dirac fermions, a candidate model for strongly interacting massive particle dark matter, utilizing Lüscher's formalism to analyze finite-volume energy levels across various fermion masses.
This lattice QCD study of and scattering near the threshold reveals weak meson interactions and finds no evidence for pole structures that would indicate the existence of a strange partner to the tetraquark.
This paper derives a frame-invariant factorization theorem for quasi-TMD distributions that incorporates all-order kinematic power corrections, revealing a non-multiplicative TMD evolution structure and demonstrating that these corrections significantly improve the agreement between lattice simulations and phenomenological extractions of the Collins-Soper kernel.
This paper employs the QCD sum rule approach with three distinct interpolating currents to predict the masses and current coupling constants of fully heavy pentaquark candidates containing three charm and two bottom quarks () or three bottom and two charm quarks () with spin-parity .
This paper presents an ongoing lattice QCD study of radiative leptonic decays for charged pseudoscalar mesons (, , , and ) using a single JLQCD ensemble, aiming to reduce theoretical uncertainties in CKM matrix element extraction and provide first-principles form factor estimates.
This paper investigates the phase structure of massless many-flavour QCD using unimproved staggered fermions to map chiral phase boundaries in the bare lattice parameter space, concluding that the continuum chiral transition is second-order for all below the conformal window and proposing methods to identify the conformal onset despite lattice artifacts.
This paper demonstrates that a one-class convolutional autoencoder trained exclusively on ground-state configurations can successfully detect the phase transition of the 3D Ising model and accurately recover its critical temperature and correlation-length exponent without prior knowledge of the system's physical parameters.
This paper presents a lattice QCD study of scalar glueball and charmonium mixing that employs improved hadron creation operators, including derivative-based meson and chromo-magnetic field glueball operators, to successfully resolve the low-lying spectrum and identify the lightest iso-scalar state as glueball-dominated.
This study utilizes QCD sum rules with nonperturbative effects up to dimension ten to predict the masses and residues of ground and excited spin-3/2 doubly heavy baryons ( and containing $cc$, $bc$, or $bb$ quarks), providing essential theoretical guidance for future experimental searches.
