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.

Automated Extraction of Collins-Soper Kernel from Lattice QCD using An Autonomous AI Physicist System

This paper demonstrates that the autonomous AI system PhysMaster can fully automate the complex, multi-step extraction of the Collins-Soper kernel from Lattice QCD data, reducing the workflow duration from months to hours while achieving precision consistent with state-of-the-art traditional methods and stabilizing signals at large transverse separations.

Exact center symmetry and first-order phase transition in QCD with three degenerate dynamical quarks

Using first-principles lattice simulations with an exact center symmetry induced by a specific imaginary isospin chemical potential, this study demonstrates that QCD with three degenerate dynamical quarks undergoes a first-order deconfinement phase transition and maps its behavior in the mass-isospin chemical potential plane.

Vector-channel scattering of dark particles in a Sp(4) gauge theory

This paper presents preliminary lattice results on the vector-channel scattering of two pseudoscalar states in an Sp(4)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.

Strange partner of Tcc+T_{cc}^+ from lattice QCD in D()Ds()D^{(*)}D_s^{(*)} scattering

This lattice QCD study of DDsDD_s^* and DDsDD_s scattering near the ccuˉsˉcc\bar{u}\bar{s} threshold reveals weak meson interactions and finds no evidence for pole structures that would indicate the existence of a strange partner to the Tcc+T_{cc}^+ tetraquark.

Analysis of Fully Heavy P(3c2b)P_{(3c2b)} and P(3b2c)P_{(3b2c)} Pentaquark Candidates

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 (3c2b3c2b) or three bottom and two charm quarks (3b2c3b2c) with spin-parity JP=12J^P=\frac{1}{2}^{-}.

Real radiative decays of heavy pseudoscalar mesons

This paper presents an ongoing lattice QCD study of radiative leptonic decays for charged pseudoscalar mesons (DD, DsD_s, BB, and BcB_c) using a single JLQCD ensemble, aiming to reduce theoretical uncertainties in CKM matrix element extraction and provide first-principles form factor estimates.
