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.
Using QCD sum rules with nonperturbative effects up to dimension twelve, this paper investigates light double-gluon hybrid mesons to determine the masses and current couplings of various , , and configurations with specific quantum numbers, providing theoretical predictions to guide future experimental searches.
This paper presents preliminary results on the electric polarizability of charged pions calculated using nHYP four-point functions with dynamical actions, smaller pion masses, and variable lattice sizes to improve upon previous quenched Wilson action studies.
This paper details the mathematical framework and numerical implementation for computing the elliptic three-loop Feynman integrals required for the hadronic vacuum polarization calculation in chiral perturbation theory, enabling fast and accurate evaluation for arbitrary complex photon virtualities.
This paper proposes a method for testing the Standard Model by applying finite-width smearing to both experimental data and lattice QCD theory predictions, thereby circumventing the significant challenges associated with extrapolating to the vanishing smearing limit required for reconstructing physical amplitudes in processes involving on-shell hadronic states.
This paper introduces an experimentally inspired method using Schmidt decompositions of the entanglement structure in Matrix Product State simulations to isolate and detect specific scattering channels, such as heavy particle production in the one-dimensional Ising field theory, without relying on prior knowledge of asymptotic particle wavefunctions.
This paper investigates strongly coupled 2D lattice QCD with three flavors, demonstrating through path integral calculations that truly gauge-invariant, conserved charges are non-zero for hadronic states, suggesting these charges are carried by hadrons and may offer new insights into the mechanism of confinement.
This paper derives a fluctuation-dissipation relation for an energetic light quark in a non-perturbative thermal gluon plasma by connecting the longitudinal drag coefficient to longitudinal and transverse diffusion coefficients and the thermal gluon condensate through complex-valued transport functions and contour-integration techniques.
This paper presents precise determinations of the relative mixing constant for the energy-momentum tensor in the 2d O(3) nonlinear sigma model using a modified lattice action and gradient flow, while highlighting that the overall normalization remains inaccessible due to significant discretization artifacts.
This paper demonstrates a viable platform for simulating the (1+1) dimensional Abelian Higgs model on superconducting transmon qutrit processors by experimentally realizing and comparing a resource-efficient pulse-based hybrid analog-digital protocol with a gate-based Trotterized approach, both leveraging the natural mapping of three-level systems to spin-1 field observables.
This paper presents a new lattice QCD determination of the tetraquark binding energy using relativistic heavy-quark actions, yielding results of approximately $-79$ MeV that are consistent with prior NRQCD findings but exhibit reduced magnitude due to the exclusive use of symmetric correlation matrices with local four-quark operators.
