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 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 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 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.
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 resolves a historical discrepancy in the definition of electric susceptibility in hot QCD by utilizing an exact fermion propagator and improved perturbation theory to demonstrate that the disagreement stems from the choice of thermodynamic ensemble and infrared regularization, while also constructing the susceptibility within a hadron resonance gas model for the low-temperature regime.
This paper introduces a flavoured lattice Schwinger model that resolves the fermion doubling problem by staggering a flavour degree of freedom, thereby preserving an exact axial symmetry at finite lattice spacing and providing a bulk-boundary interpretation of the chiral anomaly via helical edge states on a topological insulator.
This paper presents the first lattice QCD study of ground-state spin- heavy baryons containing charm and bottom quarks using fully relativistic valence quarks on physical HISQ ensembles.
This paper presents a proof-of-principle lattice QCD calculation of the charged kaon's electric polarizability using a four-point function approach on Wilson quenched lattices, yielding a value of and demonstrating the framework's applicability to strange mesons for future precision studies.
This paper presents the first lattice QCD results for bulk thermodynamics at finite baryon density with physical quark masses using a canonical ensemble approach that avoids extrapolation and the sign problem up to MeV.
