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.

False Vacuum Decay across the Quantum-to-Thermal Crossover: A Comparison of Real-Time Observables

This paper introduces a real-time Wigner-functional lattice framework with a connected-cluster survival criterion to accurately characterize false-vacuum decay rates across the quantum-to-thermal crossover, revealing that global-survival methods can underestimate rates at high temperatures due to multi-seed dynamics while transient effects contaminate fraction observables at low temperatures.

Extracting Mellin moments of double parton distributions from lattice data

This paper investigates the impact of kinematic skewness on reconstructing Mellin moments of double parton distributions from Euclidean lattice data by analyzing the skewness dependence of hadronic correlation functions through various models.

Two-nucleon systems at $m_{\pi}\approx292$ MeV from lattice QCD

Using lattice QCD with $N_f=2+1$ ensembles at a pion mass of approximately 292 MeV, this study determines finite-volume energies of two-nucleon systems in the $^3S_1$ and $^1S_0$ channels and extracts scattering amplitudes via Lüscher's method and the Non-Perturbative Hamiltonian framework, revealing that both the deuteron and di-neutron channels exhibit virtual state poles with binding energies of $6^{+5}_{-3}$ MeV and $11^{+6}_{-5}$ MeV, respectively.

Noise scheduling and linear dynamics in diffusion models on Lie groups

This paper demonstrates that diffusion models on Lie groups naturally exhibit a linear decay of the Wilson action expectation value under a specific noise schedule, a behavior that in Euclidean settings requires an explicitly designed drift term, highlighting their suitability for lattice gauge theory applications.

Variational Autoregressive Networks with probability priors

This paper proposes a Variational Autoregressive Network framework that incorporates physical priors to overcome training difficulties and critical slowing down in Monte Carlo simulations of discrete spin models, thereby enabling more efficient sampling of larger system sizes compared to "blank slate" approaches.

Extraction of spectral densities from lattice correlators: decoupling signal from noise

This paper proposes an alternative method for extracting smeared spectral densities from Euclidean lattice correlators that avoids Backus-Gilbert regularization by decomposing the solution into singular-value-like terms, allowing for optimal truncation to separate signal from noise while also serving as a tool to validate Backus-Gilbert results.

Deforming the Trail: Baseline Quantum Circuitry for $\text{SU(2)}_k$ Lattice Gauge Theory

This paper proposes a quantum circuit strategy for simulating $\text{SU(2)}_k$ lattice gauge theory by employing quantum group deformation to restore unitarity and reduce the resource scaling for two-qudit gates from $O(d^8)$ to $O(d^5)$ , demonstrating that q-deformation remains a reliable truncation method with significant advantages for quantum circuit synthesis.

Folding procedure for $Ω$ - $α$ potential

This paper investigates the bound state of the $\Omega$ + $\alpha$ system by deriving a folding $\Omega$ - $\alpha$ potential from the HAL QCD $\Omega$ - $N$ interaction, demonstrating that it fits a Woods-Saxon function and yields binding energies consistent with previous findings, while further validating the methodology through a comparative analysis of the $\Xi$ - $\alpha$ system.

Mass of the dark antibaryon using $B_d\rightarrow \Lambda \psi_{DS}$ channel in light cone QCD

This paper utilizes Light Cone Sum Rules with twist-6 contributions to calculate the branching fraction of the $B_d\rightarrow\Lambda \psi_{DS}$ decay, thereby determining the allowed mass range for the dark antibaryon $\psi_{DS}$ consistent with $B$ -mesogenesis constraints from BaBar and Belle experimental data.
