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 demonstrates that chiral-odd dimeson generalized distribution amplitudes, which encode the spin-orbit correlation in spin-zero mesons, can be experimentally accessed in reactions through the interference between leading one-photon and two-photon exchange amplitudes, offering a direct path to probe this previously unmeasured sector of meson structure at facilities like BES III.
This study employs Matrix Product States to investigate fermion discretization effects in the two-flavor lattice Schwinger model, demonstrating that twisted mass fermions offer superior convergence to the continuum limit and reduced finite-volume dependence compared to staggered and Wilson formulations, thereby validating their potential for future Hamiltonian simulations of higher-dimensional gauge theories.
This paper provides a rigorous proof that generalized Ising models with interaction parameter exhibit "entropic order" at arbitrarily high temperatures and solve NP-hard graph packing problems, leading to the emergence of a novel "entropic glass" phase on arbitrary graphs.
This paper presents a brief biography of William A. Bardeen (1941–2025), an American theoretical physicist at Fermilab renowned for his foundational contributions to the chiral anomaly, quantum chromodynamics, dynamical electroweak symmetry breaking, and heavy-light quark bound states.
This paper introduces a multiscale generative sampler that combines conditional Gaussian mixture models and masked continuous normalizing flows to overcome critical slowing down in lattice field theories, achieving significantly reduced autocorrelation times and enabling unbiased Multilevel Monte Carlo variance reduction for the two-dimensional scalar theory near criticality.
This paper compares the pion decay width in a uniform magnetic field calculated via chiral perturbation theory with lattice QCD results, finding consistency at large magnetic fields while attributing discrepancies at weak fields to differences in pion decay constants.
This paper utilizes QCD sum rule methods to model the resonance as a all-charm tetraquark in a diquark-antidiquark configuration, calculating its mass and decay widths to demonstrate consistency with experimental data and support its interpretation as a tensor state.
This paper presents an extended lattice study of SU(2) gauge theories with one and two adjoint fermion flavors, utilizing multiple methods to demonstrate that both theories reside in the conformal window with chiral symmetry unbroken, yielding continuum-limit anomalous dimensions of approximately 0.170 and 0.291, respectively.
This paper presents a lattice gauge theory formulation that successfully captures the continuum Atiyah-Patodi-Singer index for Dirac operators on domains with compact boundaries by exploiting its equivalence to the spectral flow of generalized domain-wall fermion operators, proving its validity for sufficiently small lattice spacings.
This paper critiques Henry Lamm's manuscript "Ether of Orbifolds" for incorrectly interpreting the quantity as a measure of gauge violation or departure from SU(), clarifying instead that it characterizes the shift in effective lattice spacing and that the associated claims about simulation costs are unfounded.
