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 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.
This paper presents the first systematic analysis of power corrections in the factorization of leading-twist baryon quasi-distribution amplitudes, deriving an exact closed-form relation that resums target-mass corrections to all orders and explicitly constructing next-to-leading-twist operators to quantify these effects for future lattice QCD determinations.
This paper demonstrates that intrinsic dimension, estimated via the two-nearest-neighbors method and applied to gauge-invariant variables, serves as a robust geometric diagnostic for resolving multiple, closely spaced phase transitions and identifying their associated degrees of freedom in lattice systems like the clock and Higgs models.
This retrospective Lattice QCD study demonstrates that bias-corrected machine learning models can accurately estimate chiral condensate cumulants and reduce Dirac-inversion costs to approximately 25.75% of conventional methods, provided that uncorrected estimates are adjusted to prevent amplified deviations during nonlinear reweighting.
This paper investigates meson gravitational D-form factors within the three-flavor linear sigma model to demonstrate how symmetry breaking, particularly the anomaly and flavor-dependent mass hierarchies, governs these form factors and provides sensitive probes of low-energy QCD structures.
This paper presents the first part of an SU(3)-flavour-symmetric lattice QCD study that determines the strong scattering phase shift for the channel and infers the corresponding strong phase of the weak decay, while outlining the methodology for computing the full decay amplitude in a forthcoming publication.
Using QCD sum rules, this paper investigates the masses and decay properties of the tensor hadronic molecules () and (), determining their instability against dissociation and calculating their full widths through dominant and subleading decay channels.
This paper demonstrates that Clifford-augmented matrix product states (CAMPS) enable large-scale, real-time simulations of flux tube dynamics in (2+1)-dimensional Higgs gauge theories, revealing that effective string theory accurately describes collective behavior in the rough regime while uncovering a novel long-lived prethermal regime in the strong confinement limit.
By analyzing the low-energy expansion of a 1PI effective action, this paper demonstrates that within QCD itself, it is impossible to simultaneously resolve both the and strong- problems with light quarks and a small angle, as avoiding violation at small non-zero would require the anomaly-induced contribution to the pseudoscalar mass matrix to be negligible, effectively implying the problem remains unsolved.
