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 presents the first next-to-leading order calculation of and transition form factors using soft-collinear effective theory light-cone sum rules, deriving factorization formulae, isolating excited states from ground-state contamination, and providing phenomenological predictions for branching fractions and lepton flavor universality ratios.
This paper demonstrates that dilaton effective field theory serves as a diagnostic tool to distinguish between near-conformal confining and infrared conformal gauge theories, successfully classifying the theory with fundamental fermions as confining and the theory with adjoint fermion as infrared conformal through the analysis of lattice data.
This paper demonstrates that generative diffusion models, trained on small lattice volumes and validated against hybrid Monte Carlo methods, can effectively sample near-critical lattice theories across various phases and generalize to unseen larger volumes without retraining, offering a scalable solution for large-volume sampling in lattice field theories.
This paper introduces JEPAWG, a Joint-Embedding Predictive Architecture-based weight generator that maps coupling constants directly to normalizing flow weights, demonstrating that the network's latent space can recover critical physical phenomena like phase transitions and finite-size scaling, thereby establishing network weights themselves as interpretable physical observables for lattice field theories.
This paper employs the Born--Oppenheimer effective field theory to analyze hidden-charm pentaquarks discovered by LHCb, identifying them as bound states in specific potentials, predicting their spin assignments and decay patterns, and providing the first theoretical estimates for adjoint baryon masses to be verified by future lattice QCD studies.
This paper employs the QCD sum rule method to calculate the form factors and decay widths for the semileptonic weak transition , providing theoretical benchmarks for future experimental studies of excited heavy baryon dynamics.
This paper demonstrates that nonlocal quantum field theories avoid the fermion doubling pathology because the invertibility of their entire-function operators preserves the kernel of the original Dirac operator, thereby rendering the Nielsen-Ninomiya theorem inapplicable to this nonlocal, non-compact framework.
This paper investigates truncated (1+1)D lattice gauge theories, revealing that reversing the sign of the Maxwell term induces a transition from second-order to first-order symmetry breaking, with both regimes connected by a previously overlooked supersymmetric critical point belonging to the tricritical Ising universality class.
This paper proposes a novel supervised machine learning strategy using DeepONet-like architectures to reconstruct smeared spectral functions from Euclidean correlation functions, demonstrating significant uncertainty reduction and consistency with analytic results in the 1+1-dimensional O(3) non-linear model compared to state-of-the-art algorithms.
This paper proposes a novel mechanism for achieving a naturally light composite Higgs by identifying it as a protected collective eigenmode of the strong sector's scalar kernel, characterized by specific diagnostic parameters and a microscopic sensitivity of order one, which is realized through a rank-one locking invariant and universal vectorlike bridge fermions that lift the Higgs mass only at joint two-spurion order.
