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.

This paper evaluates a machine learning framework and a novel multipoint method for the ill-posed spectral reconstruction problem by comparing them against established techniques on mock data, then applying the most effective approaches to quenched lattice data to extract the electric conductivity in the presence of a non-zero external magnetic field.
This paper presents a comprehensive global analysis of Energy-Energy Correlation data across a wide range of center-of-mass energies, utilizing N³LL resummation matched to fixed-order calculations and including non-perturbative power corrections to precisely determine the strong coupling constant and non-perturbative QCD parameters.
This paper demonstrates that a systematic perturbative approach incorporating a mass-like term for gluons in the maximal Abelian gauge successfully reproduces lattice simulation data for both non-Abelian and diagonal gluon propagators in the infrared regime of $SU(2)$ Yang-Mills theory.
This lattice QCD study demonstrates that including tetraquark operators is essential for reliably extracting the finite-volume spectrum of the and scalar mesons, as their omission leads to unreliable results and fails to reveal critical energy levels such as an additional state below the threshold.
Using the constituent quark potential model combined with the Gaussian expansion and complex scaling methods, this study systematically investigates S-wave singly heavy tetraquark systems with multiple strange quarks, finding no bound states but identifying several compact resonances in the charm and bottom sectors that decay into specific meson pairs and serve as targets for future experimental searches.
This paper introduces a novel algebraic modeling strategy for pion Generalized Parton Distributions that rigorously satisfies all QCD constraints, demonstrating through next-to-leading order calculations that gluons dominate the pion's response in deeply virtual Compton scattering at Electron Ion Collider kinematics.
This paper employs a Poincaré-covariant Dyson–Schwinger–Bethe–Salpeter framework to demonstrate that, despite the top quark's rapid weak decay, quantum chromodynamics predicts the existence of tightly correlated pseudoscalar and vector toponium bound states with masses near 345 GeV and minimal hyperfine splittings.
This paper introduces HMC, a hybrid algorithm combining Exact Diagonalization and Hamiltonian Monte Carlo that overcomes the scaling limits of ED and the sign problem of standard Monte Carlo methods to enable efficient simulations of larger 2D arrays of coupled quantum wires.
This paper presents the status of an exploratory lattice QCD calculation utilizing a dual heavy-quark strategy and the finite-volume formalism to determine the hadronic matrix elements for the resonant final state, a crucial step toward achieving precise Standard Model predictions for the decay.
The paper introduces CaRBM, a fixed-depth quantum algorithm that utilizes Restricted Boltzmann Machine block-encoding with partial correction to efficiently prepare thermal states, particularly at high temperatures, as demonstrated by its application to calculating partition function zeros and phase diagrams in the XXZ and Gross-Neveu models.
