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 two-particle-irreducible vertex of the two-dimensional lattice $\phi^4$ model across the Ising transition

This paper reconstructs the two-particle-irreducible vertex of the two-dimensional $\phi^4$ lattice model across the Ising transition using Monte Carlo data, revealing a multidimensional soft sector dominated by ferromagnetic and nematic channels, and demonstrates that approximating the fully irreducible vertex as a local contact term accurately reproduces self-energy dynamics via parquet and Schwinger-Dyson equations, thereby providing a first-principles benchmark for the dynamical local-vertex approximation (D $\Gamma$ A).

A large size of the pion-like excitations in the stringy fluid above $T_{ch}$ is model independent and required by current algebra

This paper demonstrates that the large size of pion-like excitations in the stringy fluid regime of QCD above the chiral symmetry restoration temperature is a model-independent phenomenon required by current algebra, arising from Pauli blocking effects that cause these mesons to swell significantly.

From One to Eight: Supersymmetry Restoration in Lattice 3D ${\cal N} = 4$ Super Yang--Mills

This paper demonstrates that in a lattice formulation of three-dimensional ${\cal N}=4$ super Yang--Mills theory preserving one exact scalar supersymmetry, the restoration of rotational symmetry in the continuum limit automatically ensures the restoration of the remaining seven supersymmetries, thereby eliminating the need for fine-tuning.

Anomalous Thermal Dimension and the Enthalpy Renormalization Group Flow in QCD

This paper introduces a thermodynamic scaling framework for QCD enthalpy that defines an anomalous thermal dimension, $h(T)$ , to successfully characterize the deconfinement crossover and link quantum scale anomalies to information-geometric curvature, as validated by Lattice QCD data.

Dynamic Induction of Lattice Gauge Theories on a Quantum Computer

This paper demonstrates a new paradigm for quantum simulation where Gauss's law is utilized to dynamically induce U(1) lattice gauge theory dynamics from a simpler three-body XXX model, achieving resource-efficient real-time simulations on a 101-qubit IBM processor with a fivefold reduction in entangling-gate depth compared to direct implementations.

A first look at Structured-Multiscale Algebraic Multigrid for Lattice Field Theory

This paper introduces and benchmarks Structured-Multiscale Algebraic Multigrid (SM-AMG), specifically its Aggregative-Multiscale variant (AM-AMG), as a simplified alternative to adaptive solvers for Lattice QCD, finding that while it offers comparable computational costs on fine lattices, it struggles with low-mode removal on coarse lattices and requires more fine-grid iterations.

Lattice QCD Calculation of the Pion Mass Splitting

Using the infinite volume reconstruction method on six $2+1$ -flavor domain wall fermion ensembles, this study calculates the charged-neutral pion mass splitting as $4.534(42)(43)$ MeV with exponentially suppressed finite-volume errors, achieving excellent agreement with experimental measurements.

Misconceptions About the Physics of the QCD Trace Anomaly from Renormalization in a Reducible Basis

This paper argues that the recently introduced reducible-basis renormalization method has generated misconceptions regarding the QCD trace anomaly, thereby obscuring its established, regulator-independent, and scheme-free nature and leading to flawed interpretations of nucleon mass and internal forces.

Unpolarized gluon PDF of the nucleon from lattice QCD at physical point in the continuum limit

This paper presents a state-of-the-art lattice QCD calculation of the nucleon's unpolarized gluon parton distribution function using large-momentum effective theory on 2+1 flavor CLQCD ensembles, which incorporates distillation techniques and hybrid renormalization to extrapolate results to the physical point and continuum limit.

Confinement and String Breaking in the Compact Abelian Higgs Model

This paper presents a 1+1D Compact Abelian Higgs Model simulated on qutrit sites using DMRG methods to demonstrate how a local chemical potential can be used to measure physical features like string tension and effective meson mass, thereby enabling the study of confinement and string breaking with current quantum simulation techniques.
