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.

Finite-size behavior of higher-order cumulant ratios near criticality in two-dimensional Potts models

Using Monte Carlo simulations of two-dimensional two-state and three-state Potts models, this study investigates the hierarchy of higher-order cumulant ratios near criticality and finds that, contrary to theoretical predictions for QCD, the specific ordering observed by the STAR experiment does not generically emerge in these finite statistical systems undergoing second-order phase transitions.

On electric fields in hot QCD: infrared regularization dependence

This paper resolves a historical discrepancy in the definition of electric susceptibility in hot QCD by utilizing an exact fermion propagator and improved perturbation theory to demonstrate that the disagreement stems from the choice of thermodynamic ensemble and infrared regularization, while also constructing the susceptibility within a hadron resonance gas model for the low-temperature regime.

Charged kaon electric polarizability from four-point functions in lattice QCD

This paper presents a proof-of-principle lattice QCD calculation of the charged kaon's electric polarizability using a four-point function approach on Wilson quenched lattices, yielding a value of αE=(0.988±0.534)×10−4  fm3\alpha_E = (0.988 \pm 0.534) \times 10^{-4}\;\mathrm{fm}^3 and demonstrating the framework's applicability to strange mesons for future precision studies.

Finite density lattice QCD without extrapolation: Bulk thermodynamics with physical quark masses from the canonical ensemble

This paper presents the first lattice QCD results for bulk thermodynamics at finite baryon density with physical quark masses using a canonical ensemble approach that avoids extrapolation and the sign problem up to μB≈500\mu_B \approx 500 MeV.

Search for the QCD Critical Point in High Energy Nuclear Collisions: A Status Report

This paper reviews recent STAR experiment results on net-proton multiplicity fluctuations from RHIC BES-II collisions to search for the QCD critical point by comparing fourth-order cumulant and factorial cumulant ratios with non-critical theoretical models while addressing initial volume fluctuations and outlining future research directions.

High-precision lattice determination of the interaction potential of an SU(2) solitonic dipole and comparison with perturbative QED

This paper presents high-precision lattice simulations of an SU(2) solitonic dipole in a singlet state, demonstrating that its interaction potential quantitatively reproduces the classical Coulomb law at large distances while exhibiting short-distance deviations consistent with perturbative QED and the running of the fine-structure constant.
