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 investigates the definitions of thermodynamic quantities for strongly coupled quantum systems during sudden quenches, demonstrating that while the first law holds for three candidate definitions, only two satisfy the second law of thermodynamics.
This paper introduces SESaMo, a novel normalizing flow framework that utilizes stochastic modulation to incorporate symmetry inductive biases, enabling the effective learning of both exact and broken symmetries across diverse physical and statistical models.
This paper employs QCD light-cone sum rules to calculate the static electromagnetic properties of three charm-strange molecular tetraquark candidates, revealing that their magnetic moments are dominated by light quarks while their small quadrupole moments suggest nearly spherical charge distributions, thereby providing quantitative benchmarks to distinguish molecular structures from compact multiquark interpretations.
Using lattice QCD simulations with four physical-mass quark flavors, this study determines the momentum fractions and angular momentum contributions of quarks and gluons in the proton, confirming that both the momentum and spin sum rules are satisfied in the continuum limit.
This paper derives the expansion of the generalized domain-wall fermion Dirac operator including electromagnetic corrections up to , identifying necessary contact terms and new local operator insertions (seagull vertices) to enable gauge-covariant lattice computations of radiative corrections for hadronic processes involving chiral fermions.
This paper presents a comprehensive analysis of angular coefficients in Z and W boson production at hadron colliders, demonstrating that combining NNLL transverse-momentum resummation with NLO fixed-order calculations systematically improves the description of experimental data in the intermediate region without degrading agreement elsewhere.
This paper reformulates stochastic quantization as a finite-time stochastic optimal control problem where a neural network learns a Doob-transform force to steer a reference process toward a target equilibrium distribution, thereby eliminating model bias and enabling the recovery of multimodal distributions and critical observables more efficiently than traditional equilibration methods.
This review argues that the unquenched theoretical framework, which incorporates coupled-channel effects and hadronic loops, is essential for resolving long-standing discrepancies in charmonium spectroscopy and explaining the emergence of exotic hadronic states that cannot be accounted for by traditional quenched potential models.
This paper presents a lattice QCD calculation of nucleon unpolarized second Mellin moments using four physical-mass ensembles to determine the continuum-limit contributions of quarks and gluons to the proton's momentum, angular momentum, and orbital angular momentum.
Revisiting short-range baryon-baryon potentials within the constituent quark model, this study predicts that specific flavor antidecuplet states and the system possess sufficient attraction to form dibaryon bound states as hadronic molecules, while also comparing these findings with lattice QCD simulations.
