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 presents an updated determination of light and strange quark masses in QCD with dynamical flavors using -improved Wilson fermions on CLS ensembles, featuring non-perturbative renormalization and a controlled extrapolation to the physical point across five lattice spacings.
Using lattice QCD with domain-wall and anisotropic clover quark actions, this study calculates the form factors for semileptonic decays and predicts decay rates that are higher than both previous lattice results and experimental measurements, yet consistent with approximate $SU(3)$ flavor symmetry expectations.
This paper establishes that real-time estimators for scattering observables in gapped quantum field theories are universally applicable and yield exponentially suppressed finite-volume errors through complex spectral displacement and boost averaging, thereby enabling the quantum simulation of previously inaccessible scattering phenomena relevant to hadron physics and Standard Model precision tests.
This chapter introduces the -dependence and topological properties of QCD that lead to the strong CP problem, while discussing analytical approaches for studying these features and comparing their predictions with lattice simulation results.
This paper proposes using configurational temperature as a robust, physically interpretable diagnostic tool to verify the thermodynamic consistency and reliability of Complex Langevin simulations, effectively detecting algorithmic errors and ensuring accurate results in systems plagued by the sign problem.
This paper develops and applies a gauge-invariant tensor-network toolkit based on the loop-string-hadron formulation to systematically study both static string tension and the complex dynamical processes of string breaking, including particle production and entanglement spreading, in a (1+1)D SU(2) lattice gauge theory with dynamical fermions.
This paper investigates the interplay between magic and entanglement in two-qubit systems by deriving analytical formulas and explicit state parametrizations for the Pareto frontiers of maximal and minimal magic (quantified by Rényi-2 entropy) across all levels of concurrence.
Using QCD Laplace Sum Rules with next-to-leading order perturbative corrections and dimension-six non-perturbative condensates, this study predicts a light tensor hybrid meson mass of approximately 2038 MeV, suggesting that the and/or resonances may contain a significant hybrid component, while also providing the first NLO calculation of the tensor hybrid topological charge.
This paper demonstrates that the pushforward of the product of Haar measures by the lattice Yang-Mills action exhibits a concentration of measure phenomenon converging to a Gaussian distribution, which can be utilized to recover the strong-coupling expansion.
This paper presents a precise determination of charm and bottom quark masses using a heavy-quark step-scaling strategy that connects small-volume relativistic simulations to large-volume CLS ensembles, offering a complementary approach with distinct systematic uncertainties to standard large-volume methods.
