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 presents a non-perturbative lattice determination of the baryon junction mass in -dimensional $SU(3)$ Yang--Mills theory using high-precision simulations and Effective String Theory corrections, while also confirming the Svetitsky--Yaffe conjecture by demonstrating that the system's high-temperature behavior aligns with the two-dimensional three-state Potts model near the deconfinement transition.
This paper demonstrates how to extract baryon light-front wave functions from equal-time lattice QCD correlators by proving their factorization into a three-quark color-singlet component, a residual lattice factor, and a soft factor, while also verifying the wave function's renormalizability and deriving its evolution equations.
This paper presents a one-loop computation of the quark propagator in the Curci-Ferrari-Delbourgo-Jarvis gauge with dynamical quarks, demonstrating that the framework remains infrared-stable with frozen coupling and mass parameters, while suggesting that finite gauge parameters may better align with lattice trends than the Landau gauge.
This paper investigates the impact of the violation of the non-Abelian Bianchi identity (VNABI) on QCD topology, demonstrating through both theoretical Wu-Yang arguments and lattice Monte-Carlo simulations that while VNABI introduces non-gauge-invariant terms and prevents self-dual instantons from being classical solutions, the integrated anomalous contribution vanishes, thereby preserving the consistency of topological charge and the Atiyah-Singer index theorem.
This paper diagnoses performance limitations in Rydberg-ladder gauge simulators by analyzing bitstring measurements from the Aquila platform, revealing that while readout mitigation is effective, residual errors in probability estimation are primarily driven by imperfect state preparation rather than readout noise.
This paper presents an infinite-dimensional matrix representation for arbitrary gauge-invariant operators at a trivalent vertex within the loop-string-hadron (LSH) framework for SU(3) lattice Yang-Mills theory, establishing a standalone computational approach that significantly outperforms the traditional Schwinger-boson method and includes a companion code to facilitate Hamiltonian-based quantum chromodynamics calculations.
This paper investigates the feasibility of extracting infinite-volume scattering phase shifts on quantum computers using a one-dimensional trapped system model, demonstrating that while the method yields accurate results with two qubits on IBM hardware, it currently fails with three qubits due to gate operation and thermal relaxation errors.
This paper resolves the inability of staggered-fermion discretizations to support topological phases in (2+1)D Hamiltonian lattice QED by demonstrating that Wilson fermions naturally enable nontrivial topological regimes with nonzero Chern numbers, which are characterized through gauge-invariant diagnostics and exact diagonalization to provide a foundation for near-term quantum simulations.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This paper presents a lattice QCD study of the conjectured H-dibaryon across five flavor channels and nine temperatures, revealing that the 27-plet channel yields the heaviest mass while the channel is the lightest, with binding energy relative to a pair being negative for the singlet, , and channels but positive for the 27-plet and channels.
