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.

Scattering Equations as the lowest order K-identities in the calculation of Stringy Scaling of Hard String Scattering Amplitudes

This paper explicitly proves previously proposed K-identities for n-point hard string scattering amplitudes and introduces a generating function for an infinite set of generalized K-identities, where the lowest and next-to-leading orders correspond to the scattering equations in the CHY formalism and the original K-identities, respectively, suggesting their utility for calculating higher-order amplitudes.

Scalar and tensor structures in J/ψJ/ψJ/\psi J/\psi scattering from lattice QCD

This lattice QCD study determines J/ψJ/ψJ/\psi J/\psi scattering amplitudes up to 6.6 GeV, revealing an attractive interaction in the scalar channel that may correspond to the X(6200)X(6200) and a tensor resonance in the 5S2{}^5S_2 channel with parameters compatible with the X(6600)X(6600), attributing these distinct behaviors to dominant quark rearrangement effects.

Physics-informed quantum algorithms for glueball-like excitations in a Z2\mathbb{Z}_2 lattice gauge theory

This paper presents a physics-informed quantum computing framework for a (2+1)-dimensional Z2\mathbb{Z}_2 lattice gauge theory that variationally prepares the gauge vacuum and employs Wilson-loop quantum subspace expansion, eigenvector continuation, and quench dynamics to systematically construct and characterize localized glueball-like excitations, offering a transferable approach for future non-Abelian studies.

Mixing effects in radiative decays of heavy-strange axial-vector mesons within light-cone QCD sum rules

This paper utilizes light-cone QCD sum rules to calculate the radiative decay widths of heavy-strange axial-vector mesons, demonstrating that the significant difference in decay patterns between the lower and higher states arises from the constructive and destructive interference of 1P1^{1}P_{1}-3P1^{3}P_{1} mixing, respectively.

Stability of the symmetry-protected topological phase and Ising transitions in a disordered U(1) quantum link model on a ladder

This study demonstrates that while disorder in a U(1) quantum link model on a ladder can destroy the criticality of the nonzero mass phase, the Ising universality class and the symmetry-protected topological phase remain robust against weak disorder, contrary to predictions from the Harris criterion.
