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 proposes a family of quantum walks that eliminate fermion and pseudo-doublers while simulating the Dirac equation in the continuum limit by allowing a non-zero probability for the walker to remain at the same point, despite retaining a small number of non-Dirac low-energy solutions.
This paper introduces a new Monte Carlo estimator for flow fields that utilizes coupled Langevin noise to significantly mitigate statistical noise, thereby offering a robust method for addressing critical slowing down and signal-to-noise issues in lattice field theory while also generating unbiased training data for machine learning.
This paper presents preliminary lattice QCD results for the , dibaryon using flavors at unphysical quark masses, employing the distillation technique and multiple momentum frames to determine the interacting spectrum and scattering amplitude as a step toward establishing the particle's existence at physical quark masses.
This paper presents a two-loop lattice perturbative analysis of discretization artifacts in the QCD running coupling using the background field method with clover-improved Wilson fermions and Symanzik-improved gauge actions, providing general analytical results and numerical coefficients to improve the precision of strong-coupling determinations by removing mass-dependent cutoff effects.
This paper presents a novel, robust quadrature-based framework for reconstructing spectral densities from noisy Euclidean correlators by integrating reparameterization, data smoothing, and optimization to regularize ill-conditioned inverse Laplace transformations, demonstrating its effectiveness on toy models and mock data with promising applications for lattice QCD.
This paper argues that while classical lattice QCD suffices for stable hadron masses, quantum computers offer distinct utility for calculating resonance masses and nuclear properties by overcoming classical barriers like the Maiani-Testa theorem and signal-to-noise issues, a conclusion reached through extensive collaboration with the AI model Claude.
This paper demonstrates that a qubit-regularized SU(3) lattice gauge theory on a plaquette chain admits a continuum limit governed by a parafermion conformal field theory, yielding a massive one-dimensional model of glueballs with specific mass ratios and string tension values.
Using MILC's HISQ gauge ensembles with anisotropic Clover and -improved Wilson--Clover actions, this study investigates the tetraquark spectrum across varying quark masses and operator bases, employing a modified Lüscher method to address non-analyticity near the Left Hand Cut.
This plenary talk, accepting the 2025 Kenneth G. Wilson Award, summarizes significant contributions to understanding topology in QCD and related gauge theories through algorithmic advancements to mitigate topological freezing, analyses of Dirac spectral properties, and investigations into axion phenomenology.
This paper presents new non-perturbative results on the meson spectrum and low-energy constants in large- QCD, derived from lattice Monte Carlo simulations of the Twisted Eguchi-Kawai model up to combined with standard finite- data.
