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 a hybrid classical/Rydberg atom simulator using a two-leg ladder geometry to model hadronization dynamics, demonstrating that experimentally accessible parameters can realize string fragmentation, confinement, and tunable particle production to bridge quantum real-time dynamics with classical event generation.
Using lattice QCD at the physical point with the HAL QCD method, this study calculates S-wave kaon-nucleon potentials and scattering parameters, finding no evidence for the pentaquark resonance and suggesting that P-wave components dominate the scattering channel.
This paper proposes a generic approach using spontaneous symmetry breaking to construct 3D lattice models that evade the no-go theorem and yield a single Weyl fermion in the infrared limit, demonstrating that these models form an equivalent class with gapless superconductors and superfluids across three distinct symmetry-breaking pathways.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
This paper investigates practical optimizations for the Harrow-Hassidim-Lloyd (HHL) algorithm on near-term quantum simulators, demonstrating that while Suzuki-Trotter decomposition and block-encoding strategies improve performance for sparse and moderately dense matrices respectively, the algorithm's fidelity and scalability are fundamentally constrained by matrix sparsity and condition number.
This paper introduces a differentiable, multi-scale Effective Field Theory framework that integrates renormalization-group evolution, matching, and experimental constraints to enable efficient gradient-based inference in large parameter spaces, as demonstrated through comprehensive 374-parameter SMEFT analyses.
This paper proposes a method for simulating lattice gauge theories coupled to fermionic matter on fault-tolerant quantum computers by regularizing the gauge fields using braided fusion categories and providing explicit quantum circuit constructions for the necessary anyonic and gates.
This paper argues that if the zeros replacing mirror fermion poles in symmetric mass generation phases are "kinematical" singularities, then a one-particle lattice Hamiltonian can be constructed to which the Nielsen-Ninomiya theorem applies, thereby enforcing a vector-like massless spectrum and challenging the feasibility of generating chiral fermions via this method.
This paper reviews recent lattice QCD results on strongly interacting matter under extreme conditions, focusing on the finite-temperature transition at zero baryon chemical potential, the search for a critical endpoint at finite density, and thermodynamic properties under external influences such as magnetic fields, rotation, and acceleration.
This paper presents a first-principles lattice QCD study of the resonance using Wilson-Clover ensembles, determining its mass and width at the physical point with controlled systematic uncertainties that yield results in excellent agreement with experimental values.
