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.

Phase structure of lattice QCD in the heavy quark high-density region and the three-state Potts model

By mapping the heavy quark high-density region of lattice QCD to a three-dimensional three-state Potts model with a complex external field and analyzing it via finite volume scaling and tensor renormalization group methods, the study reveals that the phase transition evolves from first-order to crossover and back to first-order as density increases, strongly suggesting the existence of a first-order phase transition in the high-density heavy quark regime of QCD.

Acoustic phonons in a magnetized vacuum? First-principle lattice results on the mass spectrum of the electroweak model in a strong magnetic field

Using numerical Monte Carlo simulations, this study demonstrates that in a strong magnetic field, the electroweak vacuum undergoes two crossover transitions into an intermediate vortex phase where a nearly massless WW boson excitation emerges as a Goldstone acoustic phonon mode associated with the vortex lattice, while Higgs and ZZ boson masses remain non-zero throughout.

Spatial Wilson Loops and Energy Loss for Heavy Quarks in Magnetized HQCD Model

Using a holographic heavy quark model, this paper investigates how external magnetic fields and spatial anisotropy affect the effective potential, string tension, and energy loss of heavy quarks in hot dense QGP, revealing magnetic catalysis in phase transitions and anisotropy-dependent deviations from the standard T2T^2 scaling of string tension.
