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 Microcanonical Hamiltonian Monte Carlo (MCHMC) and its continuous variant MCLMC, which utilize fixed-energy dynamics and specialized momentum bounces to achieve superior scalability and performance compared to standard HMC methods like NUTS.
This paper proposes a machine learning-driven method to improve lattice operators in critical systems, successfully constructing estimators with enhanced overlap to continuum conformal fields that significantly reduce finite-size corrections and yield more accurate scaling dimensions for the Ising and q=3 Potts models.
This paper proposes a novel Eigenvalue-cluster Algorithm for Matrix Monte Carlo simulations that overcomes the limitations of traditional Metropolis methods by effectively navigating eigenvalue clusters to ensure convergence to the true vacuum state.
This brief note provides a detailed explanation of the domain wall-to-overlap transformation, specifically focusing on the inclusion of the alpha parameter to improve the conditioning of the Domain Wall Operator.
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.
