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 proposes a formulation of QCD on a four-dimensional 16-cell honeycomb lattice, demonstrating through quenched simulations that its enhanced rotational symmetry significantly reduces cutoff effects and improves scaling, chiral, and topological properties compared to traditional cubic lattices, thereby enabling controlled continuum extrapolations with larger lattice spacings.
This paper uses Monte Carlo simulations to demonstrate that the critical correlation length amplitude ratio in weakly anisotropic two-dimensional scalar lattice theory depends significantly on the local interaction strength, contradicting previous claims of independence and revealing a complex interplay between lattice effects and interactions.
This paper demonstrates that the Yang-Mills gradient flow drives multiply wound SU(2) center vortices toward an Abelian core with winding reduced modulo two by revealing that while the vortex core spreads diffusively, unstable tachyonic modes grow to unwind the excess topological charge, leaving only the fundamental vortex as a stable, marginally bounded fixed point.
This paper proposes a hybrid approach for lattice field theory that combines energy-based diffusion models trained via score matching with subsequent sampling via stochastic normalizing flows or flow-transformed replica exchange, demonstrating improved scaling and exactness in scalar field theory and the O(3) non-linear sigma model.
This paper proposes that renormalization-group evolution of Standard Model Yukawa couplings points to a low-scale quark-lepton unification around – GeV, where specific mass relations naturally arise in Pati-Salam theories that predict testable vector-leptoquark couplings via conversion in nuclei.
This paper investigates the continuum limit of the two-dimensional Gross-Neveu model with Wilson fermions using information geometry, revealing that the Fisher metric distinguishes between long-distance and full-field behaviors as the lattice spacing vanishes, with irrelevant directions shrinking at different rates and the critical point residing at an infinite Fisher distance.
Using lattice methods with the HiRep code, this paper investigates the ground state spectrum of an SU(2) scalar-fermion-gauge system under the Brout-Englert-Higgs effect, finding that the spectrum remains largely unaffected by bare fermion mass variations and aligns with a weakly coupled theory exhibiting the Fröhlich-Morchio-Strocchi mechanism.
This paper investigates the generalized Schwinger model with a quartic potential, revealing a rich phase diagram featuring first- and second-order phase transitions that culminate in a tricritical Ising fixed point and infinitely many Ising critical points.
This paper presents the first continuum-extrapolated lattice results for the QCD equation of state at high temperatures and large baryon chemical potentials using complex Langevin simulations at the physical pion mass.
This paper demonstrates that the exact Onsager algebra of free lattice fermions in four-dimensional staggered, Wilson, and overlap formulations fully reproduces the chiral symmetry of the corresponding continuum theory, while revealing formulation-dependent trade-offs between the locality of algebra generators and the size of their compact subgroups.
