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.

This paper proposes and validates two quantum algorithms—imaginary-time simulation of Hermitian systems and real-time simulation of non-Hermitian systems—that overcome fast oscillatory behavior in scattering phase shift extraction by utilizing block encoding and Hadamard tests to handle non-unitary evolution without mid-circuit measurements.
This paper presents a lattice QCD calculation at physical quark masses within the LaMET framework to determine the proton's isovector helicity parton distribution function at NNLO accuracy and, for the first time, extract the twist-3 moment in the scheme.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
This paper proposes a two-point Padé approximation method that combines weak- and strong-coupling expansions to construct accurate global approximations for the two-point correlation function in lattice field theory, demonstrating superior performance across broad coupling regimes compared to standard one-point resummation techniques.
Through lattice QCD simulations, this study resolves the debate on the nature of low-lying scalar and axial-vector charmed mesons by demonstrating that the observed attractive and repulsive $SU(3)$ multiplet interactions support a hadronic molecule structure over a compact tetraquark configuration.
This paper presents a stable implementation of determinant quantum Monte Carlo simulations at large inverse temperatures by utilizing specific matrix decompositions to overcome numerical instabilities in fermion determinant evaluations and force term calculations, thereby enabling precise simulations at with computational costs scaling as .
This paper utilizes lattice QCD to investigate the QCD Anderson transition, proposing a new observable for localization at zero magnetic field that supports a vanishing mobility edge at the chiral phase transition, while preliminary results at non-zero magnetic fields suggest a non-monotonic behavior of the mobility edge and a potential reduction in the transition temperature.
This paper presents preliminary results demonstrating how 1-loop lattice perturbation theory improvement of Wilson loops enhances the precision of extracting the strong coupling constant from a reanalysis of TUMQCD (2+1)-flavor QCD static energy data.
This study utilizes leading-order covariant chiral effective field theory to demonstrate that momentum correlation functions are sensitive to coupled-channel effects, specifically revealing a repulsive interaction in the spin-triplet channel due to -- mixing, which distinguishes the model from non-relativistic and phenomenological approaches and offers testable predictions for current femtoscopic experiments.
This paper investigates a quenched SU(2)U(1) lattice gauge Higgs theory coupled to a static vector-like fermion to identify new types of gauge-invariant electrically charged and neutral states that differ from previous constructions in their field dressing, revealing that while neutral states are significantly lighter, the charged spectrum contains at least two distinct particle states with different masses.
