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.
Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for massless flavors may be described by a conformal manifold of -dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.
This paper presents a hybrid quantum-classical algorithm utilizing a universal Euler-Cartan parametrized circuit ansatz to efficiently compute non-perturbative characteristics, such as energy spectra and excitation states, of quantum field theories on lattice realizations with both short and long-range interactions.
This paper investigates the two-body nonleptonic decays of into accompanied by pseudoscalar or vector mesons using the naive factorization approach, calculating decay amplitudes across various topologies to determine rates and branching ratios for comparison with other theoretical predictions and experimental data.
Using (2+1)-flavor lattice QCD at the physical point, this study calculates the S-wave - interaction potentials via the HAL QCD method, revealing overall attraction in both spin channels that precludes the formation of a dibaryon bound state and highlighting the dominant role of spin-independent forces driven by heavy-hadron chromo-polarizability.
This paper presents the first sub-percent precision lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment, yielding a result of that is twice as precise as the 2025 White Paper estimate and shows a significant 4.8 tension with data-driven evaluations excluding the CMD-3 measurement.
This paper introduces a nonperturbative Hamiltonian framework that rigorously connects finite-volume lattice QCD spectra to experimental scattering observables, successfully demonstrating its utility by extracting robust resonance parameters for the meson through a unified analysis of coupled and systems.
This paper diagnoses performance limitations in Rydberg-ladder gauge simulators by analyzing bitstring measurements from the Aquila platform, revealing that while readout mitigation is effective, residual errors in probability estimation are primarily driven by imperfect state preparation rather than readout noise.
This paper presents an infinite-dimensional matrix representation for arbitrary gauge-invariant operators at a trivalent vertex within the loop-string-hadron (LSH) framework for SU(3) lattice Yang-Mills theory, establishing a standalone computational approach that significantly outperforms the traditional Schwinger-boson method and includes a companion code to facilitate Hamiltonian-based quantum chromodynamics calculations.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This chapter reviews the physics of lattice fermions satisfying the Ginsparg-Wilson relation, explains their connection to domain wall fermions, and outlines the methodology for numerical simulations using overlap fermions as part of the "Lattice QCD at 50 years" book.
