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.
Using the two-point QCD sum rule approach, this study analyzes the low-lying spin- spectrum and identifies the newly observed resonance as the first radial () excitation, as its calculated mass of aligns with the experimental value reported by BESIII.
This paper presents a continuum-QCD calculation of the leading-order hadronic vacuum polarization contribution to the muon's anomalous magnetic moment using Dyson-Schwinger and Bethe-Salpeter equations, incorporating strong and electromagnetic isospin breaking to yield a result of that aligns well with recent lattice-QCD determinations.
This paper investigates the application of score-based and energy-based diffusion models to learn and characterize the probability distributions sampled by complex Langevin dynamics, aiming to address the challenges of understanding stochastic processes in theories with sign problems.
This paper proposes a hardware-efficient trapped-ion protocol for simulating nonperturbative intense-field QED in 3+1 dimensions by encoding photon modes in collective phonons and Volkov-dressed fermions in ion spins, demonstrating that zero-noise extrapolation can effectively mitigate experimental noise to accurately benchmark nonlinear Breit–Wheeler pair production.
This paper demonstrates that chiral lattice fermions can be constructed from an ultra-local bosonic model via bosonization, yielding a doubler-free Dirac operator that circumvents the Nielsen-Ninomiya theorem by being non-local while still allowing for the gauging of non-anomalous symmetries.
Using 2+1 flavor domain wall fermion lattice QCD ensembles and a novel method involving a background electric field with single time-slice topological charge sampling to mitigate statistical noise and excited-state contamination, the authors calculate the neutron electric dipole moment to be fm after extrapolation to the physical point.
This paper investigates the electromagnetic properties of fully charm tetraquarks by deriving analytical expressions for significant next-to-leading-order QCD corrections to their two-photon decay amplitudes and providing theoretical predictions for their production cross sections in ultra-peripheral and electron-positron collisions.
This paper presents a renormalon-subtracted potential nonrelativistic QCD framework that combines variational and Green's function Monte Carlo methods with NNLO potentials to predict the masses of fully-heavy baryons and the binding properties of fully-heavy tetraquarks, achieving improved perturbative stability while identifying discrepancies with lattice QCD that are consistent with neglected corrections.
This paper calculates tensor-polarized parton distribution functions for the deuteron using a convolution model, revealing significant discrepancies with existing HERMES data that suggest the need for new theoretical mechanisms beyond a simple proton-neutron bound system, while providing predictions for upcoming experimental tests at Jefferson Lab and Fermilab.
Using QCD sum rules, this paper predicts the mass and decay width of the fully-beauty tensor tetraquark , concluding that while it is stable against strong decays into heavy meson pairs, it transforms into conventional particles via annihilation with a calculated width of MeV.
