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.

The origin of excited states of the Λ\Lambda baryon at the SU(3) point from Lattice QCD

This study utilizes large-volume lattice QCD simulations at the flavor-symmetric SU(3) point to identify bound states corresponding to the Λ(1405)\Lambda(1405), Λ(1380)\Lambda(1380), and Λ(1670)\Lambda(1670) resonances, subsequently employing Unitary Chiral Perturbation Theory to trace their pole trajectories to the physical point.

Flow-Based Global Proposals for Monte Carlo Sampling in SU(2) Lattice Gauge Theory

This paper introduces and validates a formally correct machine-learning-based global proposal mechanism for Monte Carlo sampling in SU(2) lattice gauge theory, demonstrating its ability to reproduce target ensembles and achieve modest efficiency gains in hybrid configurations while serving as a proof-of-principle foundation for future extensions to larger lattices and non-Abelian theories.

Theoretical Signatures of QCD Phase Transitions in Compact Astrophysical Systems

This paper combines lattice QCD, effective field theories, and multimessenger constraints to model first-order QCD phase transitions in neutron stars, predicting distinctive signatures such as twin star branches and delayed gravitational-wave frequency shifts that, while marginally consistent with current data, offer testable predictions for next-generation detectors like the Einstein Telescope.

Possible Existence of ϕ3^3_ϕH, ϕ4^4_ϕH, ϕ4^4_ϕHe, and ϕ5^5_ϕHe Nuclei

Motivated by recent HAL QCD simulations, this study employs a first-principles few-body framework to predict the existence of deeply and moderately bound ϕ\phi-mesic nuclei (ϕ4H^4_\phi\mathrm{H}, ϕ4He^4_\phi\mathrm{He}, and ϕ5He^5_\phi\mathrm{He}), demonstrating that strong short-range attraction in the 2S1/2^2S_{1/2} ϕN\phi N channel is the key binding mechanism.
