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.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper proposes and validates a "gauge cooling" protocol that utilizes mid-circuit measurements and syndrome-conditional recovery to actively suppress Gauss law violations and restore gauge invariance in quantum simulations of SU(2) lattice gauge theories, demonstrating improved fidelity under realistic noise conditions despite the failure of standard Knill-Laflamme error correction criteria.
This paper presents lattice evidence supporting the gauge-gravity correspondence in 3D maximally supersymmetric Yang-Mills theory by demonstrating that the spatial deconfinement transition temperatures for colors follow the holographic prediction .
This paper introduces the formulation of domain wall fermions in lattice QCD, demonstrating the recovery of exact chiral symmetry in the infinite fifth-direction limit, deriving the corresponding Ginsparg-Wilson operator, analyzing residual symmetry breaking for finite extents, and discussing improvements such as Möbius fermions as part of the "Lattice QCD at 50 years" book.
This study utilizes lattice QCD with staggered fermions to investigate mesonic screening correlators in an external imaginary electric field at finite temperature, revealing that low-temperature scalar masses increase with field strength while high-temperature correlators exhibit spatial oscillations determined by quark electric charges.
The paper introduces PRBench, a rigorous benchmark comprising 30 expert-curated physics tasks for evaluating the end-to-end reproduction capabilities of AI agents, revealing that current models struggle significantly with code correctness, data accuracy, and achieving successful reproduction despite their advanced reasoning abilities.
This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( and ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.
This paper demonstrates the extraction of the four form factors describing exclusive semileptonic decays using the narrow width approximation, based on RBC/UKQCD lattice QCD simulations with 2+1 flavor gauge field ensembles employing Shamir domain-wall fermions for light, strange, and charm quarks and the relativistic heavy quark action for bottom quarks.
This paper presents the first lattice-QCD determination of dimension-six four-quark matrix elements for heavy-meson lifetime ratios using gradient flow renormalization on 2+1-flavor domain-wall fermion ensembles, achieving NNLO matching to the scheme and providing precise bag parameters with a full error budget.
This paper demonstrates that the gradient flow combined with short flow-time expansion (GF+SFTX) serves as an effective renormalization procedure for calculating precise bag parameters of four-quark operators relevant to neutral heavy-meson mixing and lifetimes, successfully applying this method to six RBC/UKQCD domain-wall fermion ensembles to obtain results consistent with existing determinations while providing a robust framework for handling power-divergent mixing in future lattice computations.
