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 utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper proposes a "field digitization scaling" framework that treats the number of discrete field values as a renormalization group coupling, successfully applying it to relate the 2D classical clock model to the XY model and its quantum gauge theory counterpart to enable continuum limit analysis in quantum simulations.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed corrections to the vector coupling to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
This paper employs bond-weighted tensor renormalization group calculations to demonstrate that dimensionless partition-function ratios for the Ising and Potts models obey finite-size scaling and yield critical values consistent with conformal field theory predictions, while also revealing logarithmic corrections in the four-state Potts model.
Using QCD sum rules, this study calculates the mass and width of the axial-vector hadronic molecules and with quark content , predicting a mass of approximately 15.8 GeV and an unstable width of about 114 MeV to guide future experimental searches for fully heavy molecular structures.
This paper introduces a new universality paradigm for hybrid qubit-qumode quantum computing based on trigonometric continuous-variable gates, demonstrating their effectiveness through a deterministic ancilla-based implementation and a successful simulation of the lattice sine-Gordon model, including ground state preparation, real-time dynamics, and kink profile extraction.
This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper presents the latest hybrid determination of the hadronic vacuum polarisation contribution to the muon magnetic moment by the BMW and DMZ collaborations, achieving 0.45% precision and overturning the theoretical consensus to resolve the long-standing discrepancy with experimental measurements.
Using QCD sum rules, this study interprets the resonance as an -wave molecular pentaquark state and calculates its mass and decay properties, finding results consistent with experimental data.
