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.
The RC* collaboration utilizes their openQxD code to present preliminary baryon mass results, including the first computation of additional partially connected contributions for the baryon, from QCD+QED simulations employing C-periodic boundary conditions at an unphysical pion mass of approximately 400 MeV.
This paper presents the first lattice QCD calculation of the electromagnetic form factors for the tetraquark, providing evidence that its internal structure comprises a compact heavy diquark and a light antidiquark.
This paper presents the RBC/UKQCD collaborations' current status on calculating isospin breaking corrections to the hadronic vacuum polarization using stochastic coordinate sampling to efficiently construct all necessary Wick contractions and employing various lattice QED formulations to better estimate finite-volume uncertainties.
This paper presents a systematic QCD sum-rule analysis of charged kaons in hot and dense matter, deriving their in-medium masses and decay constants to reveal a significant mass splitting driven by baryonic interactions and identifying a critical density threshold that signals the onset of chiral symmetry restoration.
Using auxiliary-field quantum Monte Carlo simulations, this study provides precise thermodynamic benchmarks for the strongly interacting two-dimensional Fermi gas, identifying signatures of a pseudogap regime where pairing correlations persist above the superfluid critical temperature.
This paper advances the quantum simulation of massive Thirring and Gross–Neveu models with arbitrary fermion flavors by analyzing their gate complexity, classifying their dynamical Lie algebras, and successfully preparing their ground states using an adaptive-variational quantum imaginary time algorithm.
This paper demonstrates that the ground states of quantum link models with dynamical matter in and dimensions naturally reside in a specific Gauss law sector that is free of the fermion sign problem, a property that enables efficient simulation via a meron cluster algorithm.
This paper introduces sign-problem-free qubit-regularized lattice gauge theories in the monomer–dimer–tensor-network basis that successfully reproduce the confined and deconfined phases and universality classes of conventional SU(N) theories, suggesting a viable nonperturbative pathway to defining continuum limits for Yang–Mills theory.
This paper presents a comprehensive lattice formulation of Dirac operator indices using -theory and spectral flow, which overcomes the limitations of the overlap Dirac operator by enabling applications to manifolds with curved boundaries and defining mod-2 indices in both even and odd dimensions.
This paper presents a comprehensive analysis of bottom-charmed meson states using the inverse matrix QCD sum rules formalism, which successfully reconstructs hadronic spectral densities from first principles to determine masses and decay constants that align with experimental data while offering improved numerical stability and reduced systematic uncertainties compared to standard methods.
