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 presents a first-principles, continuum-limit lattice QCD determination of heavy meson light-cone distribution amplitudes (LCDAs) using the HQLaMET framework across multiple ensembles, yielding precise QCD and HQET results with total uncertainties below 30% that are consistent with experimental constraints.
This paper develops a general path-integral formalism for scalar thermal field theory in rotating equilibrium systems, demonstrating that angular momentum can significantly enhance particle production, such as Higgs boson production via dark sector couplings.
This paper applies a momentum-space Daubechies wavelet basis within the Hamiltonian framework to investigate nonperturbative dynamics in -dimensional theory, successfully reproducing the strong-coupling phase transition and demonstrating systematic convergence of the critical coupling as momentum resolution increases.
This paper reviews the QCD phase diagram at small chemical potentials, identifying three distinct regimes—the hadron gas, a "stringy fluid," and the quark-gluon plasma—which are differentiated by their symmetries, degrees of freedom, and scaling.
This paper reviews various theoretical and computational approaches—such as holomorphic extensions, dual variables, and machine learning—aimed at overcoming the sign problem in lattice field theories to better understand the QCD phase diagram and real-time dynamics.
The paper uses D-brane configurations to study the moduli space of fractional instantons on a twisted four-torus, demonstrating that this space is locally equivalent to the Higgs branch of an supersymmetric theory with a manifest hyper-Kähler structure.
This paper presents lattice QCD results for the inclusive semileptonic decay rate, providing a high-precision calculation with few-percent error that aligns with current experimental data through rigorous chiral and continuum extrapolations.
This paper calculates second- and fourth-order conserved-charge fluctuations in -flavor QCD using Möbius domain-wall fermions to study quark number susceptibilities across different quark masses and temperatures, comparing the results to hadron resonance gas models and Stefan–Boltzmann limits.
This paper benchmarks the performance of various variational quantum ansätze in simulating the Transverse Field Ising Model across one, two, and three dimensions with up to 27 spins, evaluating their expressivity and optimization capabilities in capturing ground state properties like entanglement entropy and critical phenomena.
This paper presents the first complete next-to-leading order QCD calculation for fully charm tetraquark production at hadronic collisions, incorporating gluon radiation effects through resummation and utilizing LHCb and CMS data to extract universal long-distance matrix elements and predict kinematic distributions for the and its spin-zero partners.
