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 introduces a novel numerical bootstrap framework based on moment observables that provides rigorous bounds on conformal field theory spectra, revealing new continuous families of kinks and spectral reorganizations across dimensions that are difficult to access with traditional methods.
This paper introduces an annealing scheme combined with normalizing flows to overcome ergodicity issues in the spin basis, enabling accurate and efficient simulations of the doped Hubbard model at finite chemical potential while significantly reducing statistical uncertainties compared to state-of-the-art methods.
This study provides numerically exact evidence from large-scale quantum Monte Carlo simulations that a bilayer honeycomb lattice model with symmetry undergoes a direct symmetric mass generation transition at a critical coupling, characterized by a distinct universality class and the absence of symmetry breaking or topological order.
This paper presents the first lattice QCD calculation of form factors using 2+1 flavor domain-wall fermions and an anisotropic clover action for the bottom quark, which are then utilized to provide Standard-Model predictions for the branching fractions and angular observables of the rare decays and .
Using lattice QCD calculations on MILC ensembles with overlap and NRQCD actions, this study provides strong evidence for a deeply bound doubly bottom tetraquark in the isoscalar channel while finding no conclusive evidence for a bottom-strange counterpart.
This paper presents recent lattice QCD results for hadronic screening masses at temperatures extending from the GeV scale to the electroweak scale, revealing persistent non-perturbative higher-order effects that challenge purely perturbative predictions and offer new insights into the microscopic structure of QCD under extreme thermal conditions.
This paper presents a Variational Quantum Eigensolver (VQE) approach for simulating supersymmetric quantum mechanics and studying spontaneous supersymmetry breaking, featuring an adaptive ansatz construction to reduce resource demands and demonstrating preliminary results on real IBM quantum devices with error mitigation.
This paper presents improved first-principles lattice QCD results for the smeared -ratio in isoQCD, utilizing enhanced ETMC correlation functions and the Hansen-Lupo-Tantalo method to achieve high-precision determinations with Gaussian kernel widths down to MeV.
This paper demonstrates that the choice of prescription in the Collins-Soper-Sterman framework introduces a significant intrinsic theoretical uncertainty in Transverse Momentum Dependent distribution extractions, yielding consistent results for low-energy data but causing substantial discrepancies in intermediate-to-high energy predictions.
This study employs QCD light-cone sum rules to calculate the magnetic dipole moments of hidden-charm pentaquarks using four distinct diquark-diquark-antiquark interpolating currents, demonstrating that these electromagnetic observables are highly sensitive to internal quark configurations and can effectively discriminate between compact and molecular structural models.
