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 reviews recent developments in chiral dynamics to explain how the strong attractive interaction of the kaon with nucleons and heavy-light mesons leads to the formation of hadronic molecules like the and , while predicting the existence of three-body hadronic molecules such as .
This paper reports the current status of a program aiming to determine the strong coupling constant with approximately 0.3% precision using four-flavor lattice QCD simulations in the infinite volume gradient flow scheme, while analyzing cutoff and finite-mass effects and outlining the necessary extrapolations for the final result.
Using first-principles lattice simulations with an exact center symmetry induced by a specific imaginary isospin chemical potential, this study demonstrates that QCD with three degenerate dynamical quarks undergoes a first-order deconfinement phase transition and maps its behavior in the mass-isospin chemical potential plane.
This paper presents the first lattice study of the critical bubble in the 4D SU(8) pure gauge model using multicanonical Monte Carlo simulations to determine the bubble nucleation probability, compare it with thin-wall calculations, and demonstrate the crucial role of the order parameter choice in accurately resolving the phase transition.
This paper proposes that a nonperturbative Higgs mechanism, triggered by the formation of a specific unphysical Goldstone boson and operating via the Schwinger mechanism, generates a dynamical mass for gluons in linear covariant gauges while preserving the unbroken nature of the color charge operator to ensure color confinement.
This paper introduces Scale Factorized-Quantum Field Theory (SF-QFT), a novel framework that eliminates renormalization ambiguities in QCD and QED by factorizing momentum modes and employing Effective Dynamical Renormalization with Principle of Observable Effective Matching constraints to produce scale-invariant observables and high-precision predictions with significantly reduced computational complexity compared to conventional methods.
The paper introduces PhysMaster, an autonomous LLM-based agent that integrates abstract reasoning with numerical computation and a layered knowledge base (LANDAU) to independently accelerate, automate, and discover solutions across diverse open-ended physics research tasks.
This paper utilizes the functional renormalisation group to demonstrate that the Bars-Yankielowicz class of chiral gauge theories exhibits two distinct infrared phases, including a novel large-colour regime characterized by confinement without symmetry breaking.
This paper demonstrates that four-dimensional quantum field theories with elementary self-interacting Dirac fermions are renormalizable and predictive at leading order in the large- limit, providing exact beta functions and scaling dimensions for extended four-fermion interactions including higher-derivative terms.
This paper presents six global analyses of generalized parton distributions (GPDs) at zero skewness using various modern PDF sets and factorization scales, demonstrating that NNPDF40 at NLO provides the best fit to elastic electron scattering data while revealing moderate sensitivity to PDF inputs and perturbative orders.
