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.
Using the QCD sum rule method, this paper investigates the masses, decay widths, and dominant decay channels of the hypothetical scalar molecules () and (), predicting them to be strong-interaction unstable particles with masses of approximately 15.7 GeV and 9.7 GeV, respectively, to guide future experimental searches.
This paper demonstrates that the continuum limit of specific gauged tensor networks is well-defined, yielding a new class of states suitable for the non-perturbative study of gauge theories directly in the continuum.
This work derives pressure-energy equations of state for the nucleon from gravitational form factors and the conservation of the energy-momentum tensor, revealing a fundamental balance between pressure-induced static pressure (associated with condensate depletion and confinement) and traceless dynamic pressure, while simultaneously demonstrating that the same relations also apply to vortices in type-II superconductors and the cosmological constant in the CDM model.
Using the dynamic diquark model with a Born-Oppenheimer potential derived from lattice QCD, this study predicts that the doubly heavy scalar tetraquark lies near the threshold as a potential bound state or narrow resonance, while the axial-vector state is a compact -wave resonance situated approximately 23–28 MeV above the threshold.
This paper proposes an automatic windowing procedure with a rigorous stopping criterion based on upper and lower bounds of the autocorrelation function to accurately estimate statistical errors in lattice field theory simulations, addressing the challenges of truncated integration in both traditional and master-field Monte Carlo approaches.
This work investigates the tensor form factors and quark tensor charges of the hyperons , , and within the framework of QCD sum rules and provides new non-perturbative insights into the spin structure of spin-3/2 baryons for future phenomenological and experimental studies.
This paper presents a next-to-leading order expansion formula for computing parton distribution functions from current-current correlators, which offer simple renormalization properties and avoid linear power divergences, alongside preliminary numerical results utilizing four-point functions on the lattice.
This paper predicts the existence of a lighter scalar partner, , for the recently observed tetraquark based on CMS data, urging further experimental investigation to confirm an S-wave multiplet of states and distinguish between competing theoretical models.
This paper analyzes one-dimensional theory on a lattice to demonstrate that Gaussian models fail primarily due to structured dependencies between Fourier modes rather than marginal non-Gaussianity, leading to the identification of three distinct regimes and a simple diagnostic criterion for determining when more expressive nonlinear models are necessary.
This study presents a lattice QCD calculation of the nucleon's strange electromagnetic form factors, including electric and magnetic radii and the magnetic moment, using twisted-mass fermions at the physical point and multiple lattice spacings to achieve a continuum limit with high-precision stochastic noise mitigation for disconnected contributions.
