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.

Real-time Scattering in \phi^4 Theory using Matrix Product States

This paper demonstrates that uniform matrix product states combined with the time-dependent variational principle can effectively simulate real-time two-particle scattering in (1+1)-dimensional ϕ4\phi^4 theory, revealing distinct elastic and inelastic behaviors across different phases and identifying a dynamical divergence near the critical point as a signature of the closing mass gap.

Unified Description of Pseudoscalar Meson Structure from Light to Heavy Quarks

This paper presents a comprehensive review of an algebraic light-front model that provides a unified, symmetry-consistent description of the structure of pseudoscalar mesons across light, heavy-light, and heavy-heavy quark regimes, demonstrating how increasing quark mass drives a transition from broad, asymmetric momentum distributions to compact, symmetric configurations.

Adiabatic continuity in a partially reduced twisted Eguchi-Kawai model with one adjoint Dirac fermion

This paper provides numerical evidence from a partially reduced twisted Eguchi-Kawai model that the confined phase of large-NN $SU(N)$ gauge theory with one adjoint Dirac fermion persists under spatial compactification with periodic boundary conditions, supporting an adiabatic continuity scenario between large and small circles, whereas antiperiodic boundary conditions induce a clear deconfinement transition.

Ground state preparation in two-dimensional pure Z2\mathbb{Z}_2 lattice gauge theory via deterministic quantum imaginary time evolution

This paper demonstrates that a generalized, gauge-invariant deterministic quantum imaginary time evolution (QITE) algorithm can efficiently prepare the ground state of two-dimensional pure Z2\mathbb{Z}_2 lattice gauge theory with high accuracy (relative error < 0.1%) and reduced resource costs, as validated by classical tensor network simulations against DMRG results.

Analysis of the D0(2300)D_0^*(2300) resonance from lattice QCD under chiral symmetry

This paper reanalyzes lattice QCD spectra for I=1/2I=1/2 DπD\pi scattering by incorporating chiral and SU(3) flavor symmetries, revealing that chiral corrections shift the D0(2300)D_0^*(2300) pole mass closer to threshold and reduce its width, while coupled-channel unitarized chiral perturbation theory confirms a two-pole structure for the resonance.

Finite-temperature topological transitions in the presence of quenched uncorrelated disorder

This paper demonstrates that weak quenched uncorrelated disorder induces a new topological universality class for the finite-temperature phase transition in the three-dimensional lattice Z2{\mathbb Z}_2 gauge model, consistent with the Harris criterion's prediction for the relevance of disorder in systems with a positive specific-heat critical exponent.

Comprehensive analyses of rare ΛbΛ+ \Lambda_b \rightarrow \Lambda \ell^+ \ell^-, ΣbΣ+\Sigma_b \rightarrow \Sigma \ell^+ \ell^- and ΞbΞ+\Xi_b \rightarrow \Xi \ell^+ \ell^- decays in 2HDM

This paper investigates rare dileptonic decays of Λb\Lambda_b, Σb\Sigma_b, and Ξb\Xi_b baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.
