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 framework combining lattice QCD inputs with first-order symmetry breaking to predict specific branching ratio measurements for semileptonic decays that can definitively determine whether the observed large symmetry breaking stems from unexpected hadronic mechanisms or new physics.
This paper proposes a machine learning framework to optimize the fifth-dimensional coefficients of domain-wall fermions, using a stochastically estimated residual mass as a loss function to minimize chiral symmetry violation, with feasibility demonstrated on a small lattice.
This paper introduces a robust discrete formulation for computing the three-dimensional winding number of smooth maps to using -gaps, offering both a practical unmodified flux for fine grids and a modified flux that strictly guarantees integer quantization even in the presence of degeneracies.
This paper demonstrates that in four-dimensional Causal Dynamical Triangulations coupled to $SU(N)$ gauge theories, the emergence of topological charge and semiclassical spacetime is restricted to the -phase, thereby establishing a critical link between this specific geometric phase and the existence of non-trivial gauge topology.
This paper calculates the tensor-polarized twist-3 parton distribution function for the spin-1 deuteron by applying twist-2 relations to the known twist-2 function , demonstrating that is comparable in magnitude to and suggesting that current and future facilities like JLab and the EIC are well-suited to investigate these higher-twist effects.
Using continuum Schwinger function methods, this paper demonstrates that the pion and kaon possess significant intrinsic orbital angular momentum in their rest frames and light-front projections, revealing them as complex bound states with observer-dependent OAM compositions that must be accounted for in hadronic observables.
This paper presents the first lattice-QCD estimate of the QCD crossover line down to MeV by introducing a novel method that combines Lee-Yang edge singularities from imaginary chemical potential simulations with universal chiral scaling to determine the baryon chemical potential dependence of critical temperatures without relying on small- expansions.
This paper investigates the thermodynamic geometry of the hadron resonance gas model with and without excluded volume effects across real and imaginary baryon chemical potentials, utilizing the scalar curvature to map phase structures, determine a baryon gas limitation temperature that aligns with lattice QCD predictions, and derive a simple sufficient condition for quark deconfinement.
Using tensor network methods on a hexagonal lattice, this study demonstrates that a non-Abelian SU(2) quantum link model in (2+1) dimensions is confining and exhibits a Lüscher term with a coupling-dependent coefficient alongside a logarithmically scaling string width, providing evidence for a rough string without a roughening transition across all coupling values.
This paper investigates Wilson loops containing oppositely oriented plaquettes in lattice gauge theory to probe center vortex structures, finding that while the vertical configuration aligns with vortex expectations, the parallel configuration's deviation from the naive area law is successfully explained by a new qualitative vortex model.
