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.

A gauge-invariant measure for lattice chiral fermions

This paper nonperturbatively constructs a gauge-invariant measure for overlap fermions on four-dimensional Euclidean lattices within a class of nonabelian chiral gauge theories, including the Standard Model, by demonstrating that comparing chiral projectors on admissible gauge fields yields an exponentially local current that satisfies the global properties required for Lüscher's reconstruction of a smooth fermion measure.

Sampling SU(N) gauge theory on a 2D lattice from independent plaquettes via holonomies and corner reweighting

This paper proposes a statistical sampling method for 2D SU(N) lattice gauge theory that bypasses the difficulty of mapping independent plaquettes to link variables by reformulating the problem in terms of holonomies and corner reweighting, achieving high acceptance rates and moderate effective sample sizes through a combination of normalizing flows and closed-form or trained samplers for the group commutator constraint.

Bjorken sum rule down to the elastic region from the lattice

This paper presents a lattice QCD determination of the Bjorken sum rule by calculating the lowest moment of the nucleon's polarized structure function g1g_1 across a wide range of momentum transfers (0.5≲Q2≲80.5\lesssim Q^2 \lesssim 8 GeV2^2) using the Feynman-Hellmann method, thereby enabling the study of higher-twist effects and providing an alternative hadronic evaluation of the strong coupling constant αs(Q2)\alpha_s(Q^2).

Two-pion exchange potential in D(∗)D(∗)D^{(*)}D^{(*)} system

Motivated by recent HAL QCD lattice results, this paper employs heavy-meson chiral perturbation theory to demonstrate that isospin-independent two-pion exchange contributions at next-to-next-to-leading order are crucial for reproducing the semi-long-range behavior of the DD-D∗D^* potential and predicts similar tails for other D(∗)D^{(*)}-D(∗)D^{(*)} systems.

Finite-size scaling analysis of three dimensional Z(2) and O(2) spin models with non-vanishing symmetry breaking parameter

This paper presents a high-statistics finite-size scaling analysis of 3D Z(2)Z(2) and O(2)O(2) spin models in an external field, deriving a specific parametric form for leading finite-size corrections that enables the elimination of systematic errors in determining the chiral phase transition temperature in (2+1)-flavor QCD.

Compositeness and decay properties of the flavor partner of Ds0∗(2317)D^{*}_{s0}(2317)

This paper performs a coupled-channel calculation in the hidden-gauge formalism to predict five new JP={0,1,2}+J^P=\{0,1,2\}^+ states in the bottom sector following the discovery of Bs0(5700)B_{s0}(5700), while demonstrating that the inclusion of bare components and heavy-quark-spin violating effects significantly reduces the isospin-breaking decay widths of the Bs0B_{s0} and Bs1B_{s1} states.
