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 novel supervised machine learning strategy using DeepONet-like architectures to reconstruct smeared spectral functions from Euclidean correlation functions, demonstrating significant uncertainty reduction and consistency with analytic results in the 1+1-dimensional O(3) non-linear model compared to state-of-the-art algorithms.
This paper proposes a novel mechanism for achieving a naturally light composite Higgs by identifying it as a protected collective eigenmode of the strong sector's scalar kernel, characterized by specific diagnostic parameters and a microscopic sensitivity of order one, which is realized through a rank-one locking invariant and universal vectorlike bridge fermions that lift the Higgs mass only at joint two-spurion order.
This paper employs a transverse-momentum cutoff to systematically disentangle scheme-dependent contributions from infrared divergences in the one-loop nonsinglet quark quasi-PDF, thereby clarifying the renormalization-group behavior and providing a benchmark for matching to lightcone parton distributions.
This paper investigates the spectroscopic properties of the double strange hybrid baryon ($ssqg$) using QCD sum rules with an interpolating current containing explicit gluonic degrees of freedom, yielding theoretical mass predictions of approximately 1593 MeV for the ground state and 1897 MeV for the first excited state to guide future experimental searches.
This paper presents a proof-of-principle simulation of (2+1)D quantum electrodynamics with two fermion flavors at finite density on a quantum computer, utilizing a gauge-invariant ansatz and classical optimization to identify phase transitions on IBM hardware while discussing future scalability.
This review article introduces the fuzzy sphere regularization method as an efficient tool for studying 3D conformal field theories and critical phenomena, highlighting its unique ability to reveal deep connections between noncommutative geometry, the quantum Hall effect, and the state-operator correspondence on the geometry.
This paper presents a comprehensive analysis of exclusive semileptonic decays within and beyond the Standard Model by employing Heavy Quark Effective Theory with a data-driven -expansion to predict precise lepton flavor universality ratios and evaluate the sensitivity of various observables to new physics scenarios, including the Two Higgs Doublet Model and effective field theories.
This paper introduces a Monte Carlo strategy to directly estimate partition function ratios between distinct global sectors, applying it to the critical 3D Ising model to determine the symmetry-twisted thermodynamic Casimir difference and extract CFT compactification data without relying on lattice derivatives or bulk subtractions.
This paper introduces nonperturbative gradient flow renormalization schemes for composite fermion operators using partially conserved axial and conserved vector currents to simplify lattice calculations and enable the determination of renormalization factors and the strange quark mass without requiring backward-flow constructions.
This paper presents a first-principles Lattice QCD+QED strategy to calculate isospin-breaking effects in inclusive hadronic decays, essential for improving the precision of the muon determination, by separating radiative corrections into infrared-safe classes and addressing challenges in Euclidean-to-Minkowski analytic continuation and renormalization.
