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.

Spatially inhomogeneous confinement-deconfinement phase transition in rotating QGP

Using first-principles lattice simulations, this paper reveals a novel spatially inhomogeneous phase in rotating gluon plasma where confining and deconfining regions coexist in thermal equilibrium, with the deconfined phase localized near the rotation axis and the confined phase at the periphery, a structure explained by action anisotropy in the curved co-rotating background rather than the standard Tolman-Ehrenfest law.

Universal and non-universal finite-volume effects in the vicinity of chiral phase transition in (2+1)-flavor QCD

This paper presents a finite-size scaling analysis of the chiral order parameter in (2+1)-flavor QCD using HISQ lattice data, demonstrating that infinite-volume extrapolated results align with expected $O(2)$ scaling behavior while quantifying finite-size deviations to improve the precision of chiral phase transition temperature determinations.

Symmetric Mass Generation via Multicriticality in a 3D Lattice Gross-Neveu Model

Using large-scale Monte Carlo simulations, this study demonstrates that a 3D lattice Gross-Neveu model with two four-fermion interactions exhibits a multicritical point where the direct transition to a symmetric massive phase splits into two successive transitions (Gross-Neveu and XY universality classes) separated by a symmetry-broken phase, thereby unifying conventional and unconventional fermion mass generation mechanisms.

A lattice formulation of N=2 supersymmetric SYK model

This paper presents a construction of the N=2 supersymmetric SYK model on a one-dimensional Euclidean time lattice, where one nilpotent supersymmetry is exactly preserved by utilizing the cyclic Leibniz rule.

Improved Fermionic Scattering for the NISQ Era

This paper proposes a shallow-circuit fermionic scattering state preparation method that approximates wave packets via spatial localization to reduce circuit depth by nearly half while preserving anti-commutation relations, demonstrating its efficacy through MPS simulations and successful implementation on IonQ's Forte 1 NISQ hardware.

Subthreshold parameters of $ππ$ scattering revisited

This paper utilizes experimental data, lattice QCD calculations, and Roy equation-based dispersive representations to compute the subthreshold parameters of $\pi\pi$ scattering, employing Monte Carlo sampling to quantify uncertainties and analyzing the impact of theoretical correlations between scattering lengths.

Towards a unified viewpoint of Gribov--Zwanziger and Serreau--Tissier gauge fixing

This paper proposes a unified, local, and BRST-invariant framework that interpolates between the Serreau--Tissier copy-averaged and Refined Gribov--Zwanziger gauge-fixing approaches, demonstrating their algebraic compatibility and providing a controlled mechanism to study the interplay between copy averaging and horizon suppression in infrared Yang--Mills correlators.

Unified study of $B_s^0 \to X(3872) π^+π^- (K^+ K^-)$ and $B_s^0 \to ψ(2S) π^+π^- (K^+ K^-)$ processes

This paper presents a unified theoretical description of experimental data for $B_s^0$ decays into $X(3872)$ and $\psi(2S)$ accompanied by pion or kaon pairs, utilizing unitary and analytic final-state interactions to reveal universal coupling patterns, a distinct non-charmonium nature for the $X(3872)$ , and the significant role of the $f_0(1500)$ resonance while predicting related branching fraction ratios and invariant mass distributions.

Machine Learning-Based Estimation of Cumulants of Chiral Condensate via Multi-Ensemble Reweighting with Deborah.jl

This paper demonstrates that a bias-corrected machine learning framework, implemented in Deborah.jl, can accurately estimate higher-order cumulants of the chiral condensate using only ~1% labeled data and gauge observables, reducing computational costs to 26% while maintaining statistical consistency with fully measured baselines for locating the QCD critical endpoint.

Phase diagram of the single-flavor Gross--Neveu--Wilson model from the Grassmann corner transfer matrix renormalization group

Using the Grassmann corner transfer matrix renormalization group, this study maps the phase diagram of the single-flavor Gross--Neveu--Wilson model, identifying critical lines with central charges $c=1/2$ and $c=1$ that separate the Aoki, topological insulator, and trivial phases, while finding that the Aoki phase does not persist in the strong-coupling regime.
