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.
Using fermion-bag Monte Carlo simulations, this study demonstrates that introducing a small nonzero four-fermion coupling () to a lattice fermion model qualitatively alters its phase diagram by splitting a single exotic symmetric mass generation transition into two distinct conventional transitions (Gross-Neveu and 3D XY) separated by an intermediate spontaneous symmetry breaking phase.
By combining advanced quantum Monte Carlo simulations with a novel loop estimator for Rényi entanglement entropy, this study demonstrates that an SU() generalization of the Heisenberg antiferromagnet in 1+1 dimensions exhibits weak first-order pseudocriticality driven by proximity to a complex conformal field theory, a finding that accurately recovers the real part of the complex central charge for and reinterprets the dimerized phase of the spin-1 chain as pseudocritical.
This paper demonstrates that Krylov state complexity serves as a sensitive probe of confinement in the transverse-field Ising model with a longitudinal field, revealing that confinement suppresses complexity growth and induces meson-mass-frequency oscillations, while the absence of confinement or critical transitions leads to enhanced complexity dynamics.
This paper details the computational strategy, simulations, and data analysis used to achieve a non-perturbative determination of the QCD Equation of State for three massless flavors at temperatures up to 165 GeV with approximately 1% accuracy, utilizing lines of constant physics and shifted boundary conditions to demonstrate the continued relevance of non-perturbative contributions even at the electroweak scale.
This paper presents a precise, model-independent dispersive determination of resonance pole parameters for various mesons up to 2.02 GeV by analytically continuing forward dispersion relations and global fits to scattering data, confirming established resonances below 1.7 GeV while identifying additional poles above this threshold and illustrating that resonances do not always trace full circles in Argand diagrams.
This paper presents a variational method-based mechanism, supported by numerical evidence and chiral perturbation theory, to identify and control current-enhanced excited-state contamination in lattice QCD three-point functions, particularly within the nucleon sector.
Using lattice Non-Relativistic QCD with dynamical staggered quarks, this study investigates the impact of isospin asymmetry on bottomonium states at near-zero temperature, revealing that the Upsilon mass increases at a high isospin chemical potential of while exhibiting non-monotonic behavior at lower values.
This paper introduces a reformulated electric basis and a local Krylov subspace truncation strategy for pure SU() lattice gauge theories, demonstrating that these efficient Hamiltonians remain consistent with traditional calculations at small couplings while reducing the computational resources required for quantum time evolution by 17–19 orders of magnitude.
This paper investigates a four-dimensional lattice tensor gauge theory coupled to bosonic matter using Monte Carlo simulations, revealing that while the weak coupling phase is destroyed by instanton proliferation in the pure gauge limit, distinct phases emerge for different charge values, including a single phase with a critical endpoint for and a Higgs phase recovering fractonic topological order for .
This paper reviews the current status of the muon anomalous magnetic moment as a probe for physics beyond the Standard Model following the final FNAL results and the second Theory Initiative White Paper, while discussing experimental achievements, ongoing efforts to improve theoretical predictions, and future prospects for surpassing current precision limits.
