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.
This paper employs nonperturbative Hamiltonian theory with two-particle coupled channels to extract physical electric dipole amplitudes from recent lattice QCD data on threshold pion electroproduction, while deriving a new expression for transition amplitudes that depends solely on final-state interactions.
This paper presents a scale setting and strong coupling determination for 2+1 flavor lattice QCD using HISQ ensembles, reporting precise gradient flow scales ( and ) and a potential scale () while providing a polynomial ansatz for predicting lattice spacings and estimating .
This paper demonstrates that while staggered fermions fail to capture (2+1)D topological phases in lattice QED, Wilson fermions successfully enable the realization of diverse topological states like Chern insulators and quantum spin Hall phases, thereby resolving ambiguities in Hamiltonian formulations and providing a theoretical foundation for future quantum simulations on near-term quantum computing platforms.
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.
This paper establishes universal principles and practical frameworks for simulating non-Abelian gauge theories on quantum computers by demonstrating that both gauge-singlet and non-singlet representations are valid, offering efficient circuit constructions, error analyses, and resource estimates for real-world QCD applications.
This paper introduces a generative framework based on denoising diffusion to perform model-independent, non-parametric reconstruction of proton gravitational form factors from sparse and noisy data, enabling robust extraction of chiral low-energy constants and the nucleon D-term across the full kinematic range.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper reformulates the strong coupling expansion of large- QCD as constrained one-dimensional spin chains, demonstrating that while specific subsectors remain integrable, the full system loses integrability due to zigzag symmetry constraints, yet still successfully estimates the roughening transition point.
This paper proposes that probabilistic classical field theories are equivalent to quantum field theories when formulated using fluctuating field observables, which introduce non-commuting operators and a functional integral formalism derived from classical probability laws.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
