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 a lattice QCD calculation of the charged-neutral pion mass splitting using a Pauli-Villars-regulated photon propagator to avoid power-law finite-volume effects, yielding a result of 4.56(22) MeV that agrees well with experimental measurements and validates the formalism for future electromagnetic corrections.
This paper presents lattice QCD results for the first four Mellin moments of the unpolarized parton distribution functions of the pion and kaon, computed using a physical-mass twisted mass fermion ensemble to reconstruct the valence PDFs and compare them with existing theoretical and phenomenological determinations.
This paper proposes and validates an empirical precision extrapolation method to achieve high-precision -gauge fixing in lattice QCD, successfully reproducing -dependent renormalization constants for local quark bilinear operators up to with 0.3% accuracy.
Using QCD sum rules, this study investigates the hadronic tensor molecule , calculating its mass and decay width to propose it as a viable candidate for the experimentally observed resonance .
This paper presents the first extraction of the unpolarised gluon transverse-momentum-dependent parton distribution from LHC Higgs-boson production data by fitting ATLAS and CMS measurements within a TMD factorisation framework that includes NLL accuracy and linearly polarised gluon contributions.
This study utilizes large-volume lattice QCD simulations at the flavor-symmetric SU(3) point to identify bound states corresponding to the , , and resonances, subsequently employing Unitary Chiral Perturbation Theory to trace their pole trajectories to the physical point.
This paper proposes three sample-efficient classical shadow protocols for lattice gauge theory that leverage gauge symmetry to achieve exponential improvements in sample complexity over symmetry-agnostic methods, offering a blueprint for simulating more general lattice gauge models.
This paper introduces and validates a formally correct machine-learning-based global proposal mechanism for Monte Carlo sampling in SU(2) lattice gauge theory, demonstrating its ability to reproduce target ensembles and achieve modest efficiency gains in hybrid configurations while serving as a proof-of-principle foundation for future extensions to larger lattices and non-Abelian theories.
This paper proposes a novel framework modeling topological phases of matter by embedding code-based Narain conformal field theories into critical lattice quantum field theory, utilizing Lie algebra constructions to demonstrate emergent fermionic excitations with Dirac cones characteristic of the Haldane model.
This paper combines lattice QCD, effective field theories, and multimessenger constraints to model first-order QCD phase transitions in neutron stars, predicting distinctive signatures such as twin star branches and delayed gravitational-wave frequency shifts that, while marginally consistent with current data, offer testable predictions for next-generation detectors like the Einstein Telescope.
