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 introduces a novel non-Hermitian chiral random matrix model that successfully demonstrates relativistic Cooper pairing and reproduces key features of color superconductivity, such as color-flavor locking and specific symmetry breaking patterns, within the microscopic large- limit.
This paper reports the first experimental observation of statistical localization in a Rydberg atom simulator of a lattice gauge theory, demonstrating that strong Hilbert space fragmentation can cause conserved quantities with nonlocal operator support to remain locally distributed and frozen in time, thereby challenging the expectation that such nonlocal laws do not impede local thermalization.
This paper reports the successful co-designed quantum simulation of neutrinoless double-beta decay in a 1+1D quantum chromodynamics model on IonQ's Forte trapped-ion quantum computer, where advanced compilation and error-mitigation techniques enabled the real-time observation of lepton-number violation with high precision.
This paper presents the full Lorentz decomposition of the tensor form factors for the baryon induced by both isovector and isoscalar currents, revealing distinct contributions from up and down quark components that reflect the baryon's internal structure and spin distribution.
This paper utilizes Poincaré-covariant Bethe-Salpeter wave functions to calculate pion and analogue state light-front wave functions, revealing that nonperturbative dynamical effects are significant, spin-aligned components are essential for accuracy, and Gaussian approximations fail to reliably describe transverse momentum dependent distributions at higher momentum scales.
This paper investigates the tensor form factors and quark tensor charges of the decuplet hyperons , , and within the framework of QCD sum rules, providing new non-perturbative insights into the spin structure of spin-3/2 baryons for future phenomenological and experimental studies.
This paper demonstrates that score-based diffusion models, utilizing quaternion parameterization and physics-conditioned sampling, can accurately generate SU(2) lattice gauge configurations across varying coupling strengths and lattice sizes without retraining, achieving results consistent with exact analytical predictions.
This paper proposes a viable glueball dark matter candidate arising from a confined Yang-Mills sector coupled to the Standard Model via vector-like fermion portals, developing a non-perturbative effective field theory framework that predicts a steeply scaling spin-independent scattering cross-section () within the sensitivity reach of current and next-generation xenon direct-detection experiments.
This paper introduces an autonomous AI agent framework that efficiently navigates the combinatorial design space of variational quantum circuits by iteratively proposing, training, and refining architectures to optimize performance with minimal human intervention.
This paper verifies the Atiyah-Singer index theorem for Minimally Doubled Fermions (specifically Karsten-Wilczek and Borici-Creutz formulations) in four-dimensional space-time by analyzing the zero eigenmode spectrum and spectral flow under various background gauge fields, confirming that flavored mass terms and a modified chirality operator successfully detect topological charge and assign correct chiralities to zero modes.
