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.
Towards the time-like pion form factor beyond the elastic regime using domain-wall QCD
This paper presents a preliminary lattice QCD study using domain-wall fermions to calculate the time-like pion form factor in the inelastic region by applying LSZ reduction to a three-point correlator, extending beyond the traditional elastic regime.
Topological observables and domain wall tension from finite temperature chiral perturbation theory
This paper employs SU(2) chiral perturbation theory with isospin-breaking effects to derive the QCD -vacuum solution and compute the temperature dependence of topological observables and domain wall tension up to next-to-leading order, revealing distinct monotonic behaviors for different cumulants and providing crucial theoretical insights for axion physics in hot QCD matter.
Impact of Dynamical Charm Quark and Mixed Action Effect on Light Hadron Masses and Decay Constants
This study demonstrates that including a dynamical charm quark and utilizing a mixed action setup yield light hadron properties consistent with standard 2+1 flavor calculations, with the mixed action's discretization errors potentially canceling out to improve continuum extrapolation convergence.
Quantum error mitigation by hierarchy-informed sampling: chiral dynamics in the Schwinger model
This paper introduces a novel quantum error mitigation scheme for NISQ devices that utilizes a polynomial subset of extended BBGKY hierarchy equations as a sampling criterion to effectively recover real-time chiral dynamics in the Schwinger model with polynomial resource overhead.
Constrained Symplectic Quantization: Disclosing the Deterministic Framework Behind Quantum Mechanics
This paper introduces Constrained Symplectic Quantization, a holomorphic reformulation of symplectic quantization that imposes constraints on intrinsic time Hamiltonian flow to resolve structural limitations and establish exact equivalence with the Feynman path integral, thereby enabling the accurate numerical sampling of real-time quantum observables as demonstrated on the quantum harmonic oscillator.
