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 outlines the current modernization efforts of the International Lattice Data Grid (ILDG), detailing recent advancements in metadata and middleware services tailored for large collaborations, as well as future development plans.
This paper presents a first-principles lattice QCD determination of the scalar and tensor form factors for the transition at the physical pion mass, utilizing a model-independent parametrization to constrain non-standard charged-current interactions through the muon-to-electron decay-rate ratio.
This paper introduces a method using maximally localized Wannier functions to construct unitary local dressed creation operators for the selective preparation and species-resolved detection of quasiparticle wave packets in interacting quantum lattice systems, which is validated through matrix product state simulations of scattering in hardcore Hamiltonian QCD on a ladder lattice.
This paper presents the first experimental verification of holographic duality using hyperbolic lattices, demonstrating that classical scalar field measurements in a curved bulk space successfully reproduce the boundary conformal field theory's correlation functions and entanglement entropy as predicted by the Ryu-Takayanagi formula.
This paper presents a high-precision study of the topological susceptibility in four-dimensional SU(3) pure gauge theory using seven lattice spacings and volumes to establish a controlled continuum and infinite-volume limit, yielding a precise value for the susceptibility while also providing evidence that the excess kurtosis decreases proportionally to at large box sizes.
This paper proposes an efficient framework for analyzing quantum field theories by combining a Daubechies wavelet basis with Similarity Renormalization Group flow equations to systematically decouple degrees of freedom across scales, thereby enabling the extraction of low-energy spectra from reduced-resolution Hamiltonian blocks with significantly lower computational cost.
This paper presents a minimal, resource-efficient framework for digitally simulating SU() pure Yang-Mills theory in 3+1 dimensions by combining an orbifold lattice protocol with simplified Hamiltonians and SU(2) embedding techniques, while validating these analytical improvements through Monte Carlo benchmarks to support practical quantum simulation of non-Abelian gauge theories.
This paper presents the first fully dynamical lattice QCD calculations of the dilepton decay rates and differential distributions for the charmonium transitions and , yielding results that agree with experimental data for decays but predict a rate approximately higher than current BESIII measurements.
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.
This paper proposes a -dependent coupling within a fractal Nambu–Jona-Lasinio model, calibrated against lattice QCD data, to successfully reproduce the phase diagram and experimental results from the STAR collaboration using both extensive and non-extensive statistics.
