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 proposes and validates a method for extracting Hamiltonian energy eigenvalues from quantum-generated real-time correlators using the generalized eigenvalue problem, demonstrating through simulations and hardware tests that it is substantially more efficient than Fourier transform-based approaches.
This paper demonstrates that the operator structure of the large- chiral Lagrangian induces specific correlations among low-energy constants (such as , , and ), necessitating a reinterpretation of phenomenological and lattice results in terms of these correlated directions to ensure consistent precision studies in U(3) chiral perturbation theory.
This paper numerically investigates chiral symmetry restoration in holographic QCD using a Born-Infeld black hole background, revealing that while the nonlinear electrodynamics parameter stabilizes the chirally broken phase and shifts transition temperatures, it does not alter the transition order or generate a critical endpoint within the studied range.
The authors announce the transition of their community-maintained bibliography from the "Living Review," which served as a comprehensive archive up to June 2026, to a new "Living Guide" that curates and annotates foundational work to better navigate the rapidly diversifying field of machine learning in particle physics.
This paper reports the first systematic verification of renormalization group invariance in nuclear lattice effective field theory by employing symmetry-restoring counterterms and soft regulators to achieve cutoff-independent, high-precision predictions of the He binding energy that agree with experimental values.
This paper introduces a dilated coordinate method using adaptive mesh refinement to overcome computational challenges in nuclear lattice effective field theory, enabling accelerated convergence and efficient study of weakly-bound few-body systems, exotic nuclei, and scattering processes.
This paper proposes and validates group-equivariant score-based diffusion models with an augmented training scheme to overcome critical slowing down in lattice field theory simulations, demonstrating their superior performance over generic networks in sampling two-dimensional and theories.
This study presents the first systematic QCD light-cone sum rule investigation of the electromagnetic multipole structure, including magnetic dipole, electric quadrupole, and magnetic octupole moments, for doubly strange hidden-charm pentaquarks with and , revealing significant sensitivity to internal color-spin correlations and charm-quark dominance while providing theoretical benchmarks for future experimental and lattice QCD validation.
This paper employs Born-Oppenheimer effective field theory to model quarkoniumlike states above open-flavor thresholds, revealing a spectrum organized by heavy-quark spin symmetry that includes both short-distance quarkonium resonances and long-distance molecular states, while providing multiplet assignments for experimental candidates and identifying the need for additional theoretical sectors to explain outliers.
Using finite-temperature and finite-density QCD sum rules, this study reveals that open-charm vector mesons ( and ) undergo substantial in-medium softening and significant reductions in their leptonic decay constants as baryon density increases, with the largest mass shifts reaching approximately and respectively, while finite density also lifts the vacuum degeneracy between particle and antiparticle states.
