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.

The hadronic contribution to the running of the electroweak gauge couplings

Using $N_f=2+1$ CLS lattice ensembles with a refined analysis strategy involving telescopic series and new kernel functions, this paper presents an updated, high-precision ab initio determination of the hadronic vacuum polarization contribution to the running of the electromagnetic coupling and the electroweak mixing angle, aiming to meet the projected precision requirements of future electroweak measurements at next-generation colliders.

Determination of $\alpha_S$ in the $SU(3)$ Yang-Mills theory

This paper presents a strategy to determine the running of the strong coupling in $SU(3)$ Yang-Mills theory using a finite-volume scheme with twisted boundary conditions and a gradient-flow coupling, demonstrating preliminary continuum extrapolation results that promise reduced statistical errors and the elimination of linear cutoff effects.

Worldvolume Hybrid Monte Carlo algorithm for group manifolds

This paper extends the Worldvolume Hybrid Monte Carlo algorithm to systems defined on compact group manifolds by introducing a symplectic structure on the worldvolume's tangent bundle, thereby offering a reliable and computationally efficient framework for addressing the numerical sign problem in lattice gauge theories while resolving ergodicity issues common in Lefschetz thimble approaches.

Truncation uncertainties for accurate quantum simulations of lattice gauge theories

This paper presents a new formalism for estimating truncation errors in the electric basis of lattice gauge theory simulations on quantum computers, leveraging Hilbert space fragmentation to demonstrate that errors decay factorially with field truncation, thereby improving previous error estimates by a factor of up to $10^{306}$ for models like the Schwinger model and pure U(1) gauge theory.

Gravitational $D$ -Form Factor: The $σ$ -Meson as a Dilaton confronted with Lattice Data

By fitting lattice data for nucleon and pion gravitational $D$ -form factors to a $\sigma$ -meson pole and background term, the study demonstrates that the $\sigma$ -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the $D$ -term.

Holography on the lattice: Evidence from 3D supersymmetric Yang--Mills theory

This paper presents lattice evidence supporting the gauge-gravity correspondence in 3D maximally supersymmetric Yang-Mills theory by demonstrating that the spatial deconfinement transition temperatures for $N=8$ colors follow the holographic prediction $T_c \propto \alpha^3$ .

Domain wall fermions

This paper introduces the formulation of domain wall fermions in lattice QCD, demonstrating the recovery of exact chiral symmetry in the infinite fifth-direction limit, deriving the corresponding Ginsparg-Wilson operator, analyzing residual symmetry breaking for finite extents, and discussing improvements such as Möbius fermions as part of the "Lattice QCD at 50 years" book.

PRBench: End-to-end Paper Reproduction in Physics Research

The paper introduces PRBench, a rigorous benchmark comprising 30 expert-curated physics tasks for evaluating the end-to-end reproduction capabilities of AI agents, revealing that current models struggle significantly with code correctness, data accuracy, and achieving successful reproduction despite their advanced reasoning abilities.

Magnetic moments of open bottom--charm molecular pentaquark octets

This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( $b\bar{c}$ and $c\bar{b}$ ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.

Extracting $B_s\to D_s^*\ell\nu_\ell$ form factors

This paper demonstrates the extraction of the four form factors describing exclusive semileptonic $B_s\to D_s^*\ell\nu_\ell$ decays using the narrow width approximation, based on RBC/UKQCD lattice QCD simulations with 2+1 flavor gauge field ensembles employing Shamir domain-wall fermions for light, strange, and charm quarks and the relativistic heavy quark action for bottom quarks.
