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.

Spontaneous chiral-symmetry breaking in four-dimensional QCD with $A_x=A_y=0$ projection in dimensional reduction gauge

This paper demonstrates that in four-dimensional QCD under the dimensional reduction gauge, spontaneous chiral-symmetry breaking is driven primarily by the temporal and longitudinal gauge components ( $A_t$ and $A_z$ ) while the transverse components ( $A_x$ and $A_y$ ) play no significant role, as evidenced by the preservation of the chiral condensate under $tz$-projection but its vanishing under $xy$-projection.

$N \to \Delta$ Transition Form Factors in the Thermal AdS/QCD Soft-Wall Model with Modified Propagators

This paper addresses the asymptotic divergence of the axial vector propagator in the thermal AdS/QCD soft-wall model by implementing a momentum-dependent cutoff via an interior constraint approach, thereby enabling the successful calculation of electromagnetic and axial vector form factors for the $N \to \Delta$ transition that align moderately well with experimental and theoretical benchmarks.

Towards Systematic Control of the Nucleon Gluon PDF with the Pseudo-PDF Method

This paper presents updated lattice QCD calculations of the unpolarized nucleon gluon parton distribution function using the pseudo-PDF method on a finer $2+1+1$ flavor HISQ ensemble with the Lanczos method to control systematics, revealing a strongly suppressed gluon distribution at large $x$ and demonstrating significant progress toward high-precision, systematically controlled extractions for global PDF analyses.

Onsager Algebras and Lattice Fermions

This paper demonstrates that the exact Onsager algebra of free lattice fermions in four-dimensional staggered, Wilson, and overlap formulations fully reproduces the $U(2N)$ chiral symmetry of the corresponding continuum theory, while revealing formulation-dependent trade-offs between the locality of algebra generators and the size of their compact subgroups.

Quark TMDPDFs from Large to Small $x$ : A Unified Description of CSS, DGLAP, and Small- $x$ Double Logarithms

This paper extends a full-kinematic background-field construction to quark TMDPDFs, introducing the MSTT scheme and a rapidity-only scheme that unify the description of large- and small- $x$ dynamics by simultaneously recovering CSS, DGLAP, and small- $x$ double logarithmic evolutions within a single framework.

Digital Quantum Simulation of Dynamics in Interacting Fields

This dissertation establishes a scalable framework for digitally simulating real-time dynamics in 1+1-dimensional SU(2) lattice gauge theory and $\lambda\phi^4$ models on IBM quantum hardware, utilizing physics-informed circuits and Sequency Hierarchy Truncation to overcome resource limitations while validating results against classical benchmarks.

The Standard Model on a finite bosonic lattice with continuum Weyl fermions

This paper proposes a finite-regulator formulation of the Standard Model where gauge and Higgs fields are defined on a finite bosonic lattice while quarks and leptons remain as continuum Weyl fermions, thereby preserving continuum anomaly structures and enabling a gauge-invariant, finite functional integral without requiring a finite-dimensional discretization of chiral fermions.

Magnetic monopoles produced by first-order phase transition

This paper presents the first 3D lattice simulations of magnetic monopole production from a first-order phase transition, establishing quantitative relationships between initial conditions and residual abundance while characterizing their associated magnetic and gravitational wave spectra, ultimately concluding that such monopoles cannot be the origin of primordial cosmic magnetic fields due to blazar constraints and determining their allowed mass range under Parker and dark matter bounds.

Progress on meson-glueball mixing in lattice gauge theories coupled to fermions in multiple representations

This paper presents preliminary lattice QCD results demonstrating the first evidence of meson-glueball mixing in ${\rm Sp}(4)$ gauge theory with fermions in fundamental and two-index antisymmetric representations, while also refining previous determinations of energy eigenstates and mixing angles in the flavor-singlet pseudoscalar sector.

Cavity models of non-Abelian gauge theories

This paper proposes a cavity quantum electrodynamics framework for non-Abelian SU(2) gauge theories that utilizes localized bosonic modes to model glueball formation and many-body phenomena, offering a pathway for experimental exploration of these particle physics concepts using superconducting quantum circuits.
