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.
This paper proposes a singular-value-decomposition-free method for constructing initial tensor networks and demonstrates that while Tensor Renormalization Group (TRG) results depend heavily on these initial tensors, this dependence can be eliminated and numerical robustness significantly improved by employing the boundary TRG technique.
This paper proposes and demonstrates a method using tensor network states within the Hamiltonian formalism to accurately compute parton distribution functions for the vector meson in the massive Schwinger model directly in Minkowski space, thereby overcoming the limitations of Euclidean lattice calculations and offering a pathway for quantum simulations.
This paper demonstrates that specific multipartite entanglement quantities, constructed from strong subadditivity, weak monotonicity, and conformal properties, serve as highly efficient and localized indicators for identifying critical points in 1+1D quantum systems, with their detection capabilities further enhanced by a mutual information-based lower bound and a filtering process.
This paper reviews the progress of functional QCD over the past decade in describing the phase structure of QCD, with a primary focus on predicting new phases and their experimental signatures at high densities () while addressing technical strategies, systematic errors, and validation against lattice QCD.
This paper employs both machine learning techniques and an extended analytical mass formula to predict the mass spectra of fully-heavy baryons and exotic pentaquarks, offering complementary insights that align with existing experimental data and guide future searches for unobserved states.
Using the gradient flow exact renormalization group (GFERG) within the large approximation, this paper demonstrates that a manifestly gauge-invariant non-perturbative ansatz for the 1PI Wilson action in quantum electrodynamics preserves exact gauge invariance under renormalization group flow, yielding gauge-invariant critical exponents and an infrared fixed point action for spacetime dimensions .
This paper uses infinite matrix product state techniques to demonstrate that coupling a quantized axion field to the massive Schwinger model in a Hamiltonian lattice gauge theory dynamically relaxes the effective -angle to a CP-conserving minimum, thereby providing a nonperturbative, quantum-hardware-ready solution to the strong CP problem.
This paper presents the first lattice QCD study of -meson nucleon scattering at the physical point using the HAL QCD method, revealing that while the interaction features a short-range repulsive core and a shallow attractive pocket with the channel being more attractive than , no bound states (pentaquarks) are found in either isospin channel.
This Letter presents an improved, model-independent calculation of radiative corrections to decays that incorporates structure-dependent effects beyond point-like pions and threshold enhancements, thereby refining the precision of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment derived from tau decay data.
This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.
