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.

Comprehensive analyses of rare ΛbΛ+ \Lambda_b \rightarrow \Lambda \ell^+ \ell^-, ΣbΣ+\Sigma_b \rightarrow \Sigma \ell^+ \ell^- and ΞbΞ+\Xi_b \rightarrow \Xi \ell^+ \ell^- decays in 2HDM

This paper investigates rare dileptonic decays of Λb\Lambda_b, Σb\Sigma_b, and Ξb\Xi_b baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.

Scalar and Tensor Form Factors for Λpνˉ\Lambda \rightarrow p\ell \bar{\nu}_\ell from Lattice QCD

This paper presents a first-principles lattice QCD determination of the scalar and tensor form factors for the Λp\Lambda \to p 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.

Testing holographic duality in hyperbolic lattices

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.

An efficient Wavelet-Based Hamiltonian Formulation of Quantum Field Theories using Flow-Equations

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.

A minimal implementation of Yang--Mills theory on a digital quantum computer

This paper presents a minimal, resource-efficient framework for digitally simulating SU(NN) 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.

Finite-size behavior of higher-order cumulant ratios near criticality in two-dimensional Potts models

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.

On electric fields in hot QCD: infrared regularization dependence

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.
