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 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.
This paper presents high-precision quantum Monte Carlo simulations of the two-dimensional spin-1/2 Heisenberg antiferromagnet on square lattices, yielding significantly improved ground state parameters such as energy density and sublattice magnetization that quantitatively confirm chiral perturbation theory predictions while also characterizing finite-size corrections and boundary effects.
This paper introduces a flavoured lattice Schwinger model that resolves the fermion doubling problem by staggering a flavour degree of freedom, thereby preserving an exact axial symmetry at finite lattice spacing and providing a bulk-boundary interpretation of the chiral anomaly via helical edge states on a topological insulator.
This paper presents the first lattice QCD study of ground-state spin- heavy baryons containing charm and bottom quarks using fully relativistic valence quarks on physical HISQ ensembles.
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 and demonstrating the framework's applicability to strange mesons for future precision studies.
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 MeV.
This paper introduces a link-enhanced matrix product operator (LEMPO) construction that enables the study of abelian and non-abelian lattice gauge theories on infinite one-dimensional lattices by representing their Hamiltonians in a local, translation-invariant form, as demonstrated through applications to the Schwinger model and adjoint QCD.
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.
Using anisotropic lattice QCD ensembles with Wilson-clover fermions, the study finds evidence for the effective restoration of symmetry at a temperature of MeV, which is significantly higher than the chiral crossover temperature.
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.
