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 analytically identifies Gauss law sectors in U(1) quantum link models that are free of the fermion sign problem, revealing that the ground state corresponds to a quantum dimer model with mobile monomers while the conventional zero-charge sector maps to a fully packed loop model, thereby enabling efficient Monte Carlo simulations of specific low-temperature phases.
This paper presents a high-precision first-principles calculation of the hadronic running of electroweak gauge couplings using lattice QCD and the Euclidean split technique, achieving a determination of the electromagnetic coupling at the Z-boson mass scale that is more than twice as precise as recent phenomenological estimates and reveals a significant deviation from -based results at low energy.
This paper summarizes recent developments, opportunities, and persistent challenges in reconstructing smeared spectral functions from Euclidean correlators in lattice QCD, a crucial step for calculating various physical observables despite the intrinsic difficulties of the ill-posed inverse problem.
The authors propose Gaussian Mixture Model (GMM)-based scalar potentials that combine the efficient sampling advantages of spin models with the ability to capture radial fluctuations, thereby enabling the study of spontaneous symmetry breaking and critical phenomena within the same universality classes as standard scalar theories.
This paper extends previous lattice QCD studies of Double Parton Distributions by investigating their dependence on lattice artifacts, including finite volume effects, lattice spacing, and mass parameters, using Wilson-Clover fermion ensembles from the CLS collaboration to improve precision for Standard Model background predictions at the HL-LHC.
This paper analytically and numerically demonstrates the equivalence between the three-body formalism and the two-body left-hand cut approach for resolving exchange singularities in lattice QCD, while highlighting that exponentially suppressed finite-volume effects neglected by both methods can significantly compromise amplitude extraction at small lattice volumes.
This paper constructs helicity-conditioned statistical states for a Whitney-discretized electromagnetic field on a closed three-manifold, deriving explicit information-geometric properties such as Fisher information and relative entropy to characterize these states as conditioned inferences rather than dynamical equilibria.
This paper investigates the metastability and accretion dynamics of fuzzy spheres in a three-matrix model, revealing that while single spheres are stable, concentric "onion-like" configurations become increasingly long-lived due to logarithmically growing stiffness, with transition rates quantitatively matching one-loop effective action predictions driven by sphere center fluctuations.
This review provides a pedagogical overview of the strong CP problem, detailing the standard Peccei-Quinn solution involving the QCD axion while also summarizing recent developments in alternative theoretical approaches and their phenomenological status.
This paper presents a quantum simulation of adjoint string breaking in a truncated SU(2) lattice gauge theory on an 8x8 and 16x8 triangular lattice using all 156 qubits of the ibm_boston device, achieving quantitative agreement with tensor network results and identifying non-Abelian signatures in oscillation rates and glueball production.
