hep-lat papers | Gist.Science

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.

Nucleon Parton Distribution Functions from Boosted Correlations in the Coulomb gauge

This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.

Repulsively Bound Hadrons in a $\mathbb{Z}_2$ Lattice Gauge Theory

This paper demonstrates that resonant pair-production terms in a $\mathbb{Z}_2$ lattice gauge theory enable the formation of stable, high-energy "repulsively bound" hadrons through a novel dynamical mechanism, a finding supported by matrix product state simulations and an effective model that suggests experimental realization on modern quantum hardware.

Gaussian Processes for Inferring Parton Distributions

This paper demonstrates that Gaussian Process Regression provides a robust, non-parametric Bayesian framework for reconstructing parton distribution functions from lattice QCD data, offering controlled uncertainty estimates and reduced model bias compared to traditional functional forms.

$D\bar{D}$ interactions are weak near threshold in QCD

Using lattice QCD to study coupled-channel $\eta_c\eta - D\bar{D}$ scattering, the authors find that $D\bar{D}$ interactions are weak near threshold and show no evidence of bound states or resonances between the $\chi_{c0}(1P)$ state and the $D_s\bar{D}_s$ threshold.

Simplicity of confinement in SU(3) Yang-Mills theory

The paper introduces a new topological observable called "simplicity," based on the Betti numbers of Abelian monopole current loops in SU(3) Yang-Mills theory, which provides a more accurate determination of the deconfinement temperature and serves as a potential new order parameter for studying the phase structure of QCD.

Numerical Evaluation of a Soliton Pair with Long Range Interaction

This paper numerically evaluates the interaction energy between finite-sized topological solitons (monopoles) to demonstrate how their physical dimensions cause deviations from the standard Coulomb potential at short distances, drawing a comparison to the running coupling constant in perturbative QED.

Investigation of the ensemble of maximal center gauge

To address the problem of underestimating string tension in center vortex detection, this paper proposes replacing unrestricted maximization in Maximal Center Gauge with a maximization restricted to the Gaussian-distributed part of the local gauge maxima ensemble.

Three-qubit encoding in ytterbium-171 atoms for simulating 1+1D QCD

This paper proposes a resource-efficient method for simulating 1+1D quantum chromodynamics by encoding three qubits—representing quark color—within the electronic, nuclear, and motional states of individual ytterbium-171 atoms.

Lattice QCD Determination of the Collins-Soper Kernel in the Continuum and Physical Mass Limits

This paper presents a first-principles lattice QCD determination of the Collins-Soper kernel at the continuum and physical mass limits, providing a precise nonperturbative constraint on its long-distance behavior that bridges lattice calculations with phenomenological TMD studies.

Hadronic contributions to $a_μ$ within Resonance Chiral Theory

This paper reviews recent progress in calculating the hadronic contributions to the muon's anomalous magnetic moment—specifically hadronic vacuum polarization and hadronic light-by-light scattering—using Resonance Chiral Theory, finding results consistent with the White Paper 2 values.
