hep-lat papers | Gist.Science

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.

Dense and Cold Magnetized Quark Matter: A Review of Magnetic-Field-Independent Regularization and the Medium Separation Scheme

This paper reviews and advocates for Magnetic-Field-Independent Regularization (MFIR) and the Medium Separation Scheme (MSS) as essential frameworks for studying magnetized dense quark matter, demonstrating that these methods eliminate unphysical artifacts found in traditional schemes and reveal that superconducting phases persist at zero temperature even under strong magnetic fields.

Configurational Temperature in Matrix Models and Random Matrix Ensembles

This paper investigates the configurational temperature estimator in various matrix models and random matrix ensembles, demonstrating that it satisfies the exact Schwinger–Dyson identity $\beta_{\rm config} = 1$ and serves as a sensitive diagnostic tool for Monte Carlo simulations.

Spectral densities from Euclidean correlators via integral transforms: theoretical framework

This paper presents a theoretical framework using integral transforms to derive analytic formulae for extracting spectral densities from Euclidean correlators, addressing both continuum and lattice scenarios while providing rigorous bounds to control errors arising from finite temporal extents.

Real poles with opposite-sign residues in the non-perturbative quark propagator

By dynamically coupling the quark gap equation to the full non-perturbative quark-gluon vertex, this study reveals that sub-GeV time-like momenta yield a pair of real poles with opposite-sign residues—governed by a dominant triplet of vertex form factors—thereby resolving the conceptual issues of complex conjugate poles while maintaining consistency with color confinement.

Neural-Network extraction of TMDs with SIDIS data

This paper presents the first global analysis of unpolarized Transverse-Momentum-Dependent (TMD) distributions using a neural-network parametrization that simultaneously incorporates Drell-Yan and SIDIS data at N $^3$ LL accuracy, demonstrating that the inclusion of SIDIS data broadens the extracted TMDs while reducing uncertainties compared to Drell-Yan-only analyses and offering a model-independent framework for future high-precision experiments.

Comment on "Chiral symmetry restoration, the eigenvalue density of the Dirac operator, and the axial U(1) anomaly at finite temperature"

This paper challenges the conclusions of Aoki, Fukaya, and Taniguchi regarding the vanishing of the Dirac spectral density and topological susceptibility in the chirally symmetric phase, arguing that a critical step in their proof is unjustified and their results require reassessment.

Probing Probability Geometry with Schwinger--Dyson Identities: Score Mismatch, Fisher Information, and Configurational Temperature

This paper establishes a unified geometric framework for non-equilibrium sampling by demonstrating that violations of Schwinger--Dyson identities are governed by a single score-mismatch field, thereby linking relative Fisher information, configurational temperature, and Stein operators through a variational characterization of probability distortions.

Exponential speedup in quantum simulation of Kogut-Susskind Hamiltonian via orbifold lattice

This paper demonstrates that the Kogut-Susskind Hamiltonian emerges as the infinite scalar mass limit of the more efficient orbifold lattice formulation, thereby resolving implementation challenges and enabling digital quantum simulations of SU( $N$ ) Yang-Mills theories with exponential speedup over classical and prior quantum methods.

Analytic electromagnetic signatures of compact pentaquark structure: A multi-current QCD light-cone sum rules analysis of the $P_{\psi s}^{\Lambda}$ states

This paper employs multi-current QCD light-cone sum rules to derive distinct analytic electromagnetic signatures, specifically a light-quark magnetic moment ratio of $\mu_u/\mu_d = -2$ and a vanishing charm contribution for specific currents, which serve as falsifiable tests to distinguish compact pentaquark structures from hadronic molecules.

Gluon Gravitational $D$ -Form Factor: The $σ$ -Meson as a Dilaton Confronted with Lattice Data II

This paper utilizes lattice QCD data to demonstrate that the gluon gravitational form factors of various hadrons are well-described by a dilaton effective theory where the $\sigma$ -meson acts as a pseudo-Goldstone boson of spontaneously broken scale symmetry, thereby supporting the existence of an infrared fixed point in QCD dynamics.
