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 constructs a set of conserved non-singlet charges for the 3+1 dimensional staggered fermion Hamiltonian by decomposing fermions into Majorana components and utilizing lattice translation symmetries, demonstrating that while these charges are non-commutative on the lattice, they generate axial SU(2)_L × SU(2)_R transformations in the continuum limit.
This paper reconstructs vector and axial charge operators within the Wilson fermion formalism to formulate a lattice gauge theory with exact axial symmetry and quantized chirality, enabling the study of Symmetric Mass Generation in 3-4-5-0 models.
This paper presents ongoing lattice studies of two-dimensional maximally supersymmetric Yang-Mills theory, including the construction of a supersymmetry-preserving lattice action and the development of new simulation routines, to facilitate numerical tests of gauge-gravity duality and explore non-perturbative phenomena.
Using high-statistics lattice QCD simulations with twisted mass fermions at physical quark masses, the authors determine non-zero nucleon strange electromagnetic form factors and radii in the continuum limit while finding the charm electromagnetic form factors consistent with zero.
This paper presents the first continuum-limit calculation of nucleon strange electromagnetic form factors using lattice QCD simulations with physical quark masses, yielding results with statistical and systematic uncertainties an order of magnitude smaller than current experimental determinations.
This paper presents an updated determination of light and strange quark masses in QCD with dynamical flavors using -improved Wilson fermions on CLS ensembles, featuring non-perturbative renormalization and a controlled extrapolation to the physical point across five lattice spacings.
This paper establishes that real-time estimators for scattering observables in gapped quantum field theories are universally applicable and yield exponentially suppressed finite-volume errors through complex spectral displacement and boost averaging, thereby enabling the quantum simulation of previously inaccessible scattering phenomena relevant to hadron physics and Standard Model precision tests.
This paper proposes using configurational temperature as a robust, physically interpretable diagnostic tool to verify the thermodynamic consistency and reliability of Complex Langevin simulations, effectively detecting algorithmic errors and ensuring accurate results in systems plagued by the sign problem.
This paper presents a precise determination of charm and bottom quark masses using a heavy-quark step-scaling strategy that connects small-volume relativistic simulations to large-volume CLS ensembles, offering a complementary approach with distinct systematic uncertainties to standard large-volume methods.
This paper introduces "resolution refinement," an efficient method for bootstrapping quantum eigenstate preparation by adiabatically evolving states from low-resolution to high-resolution Hamiltonians, achieving favorable scaling with system size by preserving the structure of low-energy eigenstates.
