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.

Chiral symmetry breaking for large "Nf" and the properties of the "rho" meson near the conformal window

This paper investigates how the ground-state properties of the ρ\rho meson evolve as the number of light-quark flavors (NfN_f) approaches the conformal window, revealing that while chiral symmetry restoration and deconfinement occur at a critical flavor number, the ρ\rho meson's survival is governed by the divergence of the confinement length scale rather than mass crossing, resulting in a larger, rounder object with flattened form factors and an expanding charge radius.

Determination of charged pion unpolarised TMDPDFs from Drell-Yan measurements

This paper presents an extraction of unpolarised transverse momentum dependent parton distribution functions for valence quarks in the pion by applying TMD factorisation to Drell-Yan experimental data, utilizing recent perturbative results and a precise nucleon TMDPDF to derive findings consistent with previous phenomenological and lattice computations.

Renormalized Polyakov loop in accelerated gluodynamics

This paper investigates accelerated gluodynamics via lattice simulations in Rindler coordinates to derive a renormalization prescription for the Polyakov loop and compares the resulting static quark properties with a non-accelerated approximation based on the Tolman-Ehrenfest law, finding good agreement near the critical temperature but deviations at higher temperatures likely due to corrections in the Rindler framework.

Tensor-polarized twist-3 distribution function fLTf_{LT} of spin-1 deuteron

This paper derives a Wandzura-Wilczek-like relation and a Burkhardt-Cottingham-like sum rule connecting the twist-2 and twist-3 tensor-polarized partonic structures of the spin-1 deuteron, and uses HERMES data to phenomenologically estimate that the twist-3 distribution fLTf_{LT} is comparable in magnitude and shape to the twist-2 distribution f1LLf_{1LL}, suggesting significant subleading-twist effects for future low-Q2Q^2 experiments.

Properties of the positive and negative parity charm-strange and bottom-strange mesons DsD_s, Ds∗D_s^*, Ds0∗D_{s0}^*, Ds1D_{s1}, BsB_s, Bs∗B_s^*, Bs0∗B_{s0}^*, Bs1B_{s1} from lattice QCD: masses, decay constants, and compositeness

This paper presents a comprehensive lattice QCD study using RBC/UKQCD ensembles to determine the masses, decay constants, and compositeness parameters of positive- and negative-parity charm-strange and bottom-strange mesons, providing the first lattice results for fBs0∗f_{B^*_{s0}} and fBs1f_{B_{s1}} and confirming that the positive-parity states are predominantly molecular in nature.
