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.

Weak and Higgs physics from the lattice

This paper reports on ongoing lattice investigations using a two-generation lepton setup to explore the spectrum, internal structure, and spectral functions of the weak and Higgs sectors, aiming to reconcile non-perturbative gauge-invariant results with perturbative phenomenology via the Fröhlich-Morchio-Strocchi mechanism and ultimately compare theoretical cross sections with experimental data.

Probing the chiral and U(1)U(1) axial symmetry restoration via meson susceptibilities in holographic QCD

Using a soft-wall holographic QCD model calibrated to reproduce the physical pion mass and pseudocritical temperature, this study demonstrates that while chiral symmetry restoration is clearly signaled by the degeneracy of chiral partner meson screening masses near TpcT_{\rm pc}, the restoration of U(1)U(1) axial symmetry occurs at a distinctly higher temperature (T0.190T \sim 0.190 GeV), highlighting a qualitative limitation of the model in describing the U(1)U(1) axial anomaly compared to Lattice QCD.

Factorizing the position-space photon propagator in QED corrections to lattice QCD correlators

This paper addresses the computational challenge of evaluating electromagnetic corrections to lattice QCD correlators by introducing and comparing factorization techniques for the position-space photon propagator that reduce the volume-squared complexity of the required sums, with applications demonstrated for hadronic vacuum polarization and the hadronic light-by-light contribution to the muon (g2)(g-2).

Recent update of nucleon axial-vector charge with the PACS10 superfine lattice

This paper presents an ongoing update of the nucleon axial-vector charge using the superfine lattice ensemble of the PACS10 gauge configurations at the physical point, while also examining low-energy relations derived from the PCAC relation to verify the consistency of lattice QCD data with continuum physics.

Out-of-equilibrium percolation transitions at finite critical times after quenches across magnetic first-order transitions

This paper demonstrates that quenching two-dimensional Ising-like systems across their magnetic first-order transitions induces an out-of-equilibrium percolation transition at a finite critical time, where the resulting critical behavior exhibits random-percolation scaling for cluster geometry but features a field-dependent exponent and a spinodal-like exponential dependence on the magnetic field strength.

Dimensional Expressivity Analysis, best-approximation errors, and automated design of parametric quantum circuits

This paper introduces dimensional expressivity analysis, a hybrid quantum-classical method for identifying and removing redundant parameters in parametric quantum circuits to optimize their expressivity and minimize noise, thereby enabling the automated, on-the-fly construction of efficient circuits for variational quantum simulations.
