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.

Modulated symmetries from generalized Lieb-Schultz-Mattis anomalies

This article establishes a unified, non-perturbative framework demonstrating that spatially modulated symmetries and their associated dipole algebras naturally emerge from the gauging of ordinary symmetries in the presence of generalized Lieb-Schultz-Mattis anomalies, and provides explicit lattice models as well as field-theoretic descriptions across arbitrary spatial dimensions.

The Angular Observables of ΛbΛc(Λ0π+)τ(πντ)νˉτ\Lambda_b \to \Lambda_c(\to \Lambda^0 \pi^+) \, \tau^-(\to \pi^- \nu_\tau)\, \bar{\nu}_\tau within the Paradigm of FCCC Anomalies

This contribution presents a global analysis of BB-meson flavor anomalies extended to the baryonic sector and demonstrates that the decay Λb0Λc+(Λ0π+)τ(πντ)νˉτ\Lambda_b^0 \to \Lambda_c^+(\to \Lambda^0 \pi^+) \tau^-(\to \pi^- \nu_\tau)\bar{\nu}_\tau provides a powerful, independent probe for New Physics, with the (CVL,CSR)(C_{V_L}, C_{S_R}) scenario identified as the most favored solution and specific angular observables serving as highly sensitive indicators for potential CP-violating or CP-conserving dynamics.

Determination of the Zc(3900)Z_c(3900) and the Zcs(3985)Z_{cs}(3985) states from joint analysis of experimental and lattice data

This paper presents a unified analysis of experimental and lattice QCD data that confirms the Zc(3900)Z_c(3900) and Zcs(3985)Z_{cs}(3985) as SU(3) flavor partner resonance states with specific pole masses and widths, while revealing that their internal structure requires significant components beyond simple meson-meson molecules.

Determination of heavy meson light-cone distribution amplitudes: theoretical framework and lattice simulations

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.

Hamiltonian formulation of the 1+11+1-dimensional ϕ4ϕ^4 theory in a momentum-space Daubechies wavelet basis

This paper applies a momentum-space Daubechies wavelet basis within the Hamiltonian framework to investigate nonperturbative dynamics in 1+11+1-dimensional ϕ4\phi^4 theory, successfully reproducing the strong-coupling phase transition and demonstrating systematic convergence of the critical coupling as momentum resolution increases.

Inclusive semileptonic DsXsνˉD_s\to X_s\ell\bar\nu decays from lattice QCD: continuum and chiral extrapolation

This paper presents lattice QCD results for the inclusive semileptonic DsXsνˉD_s \to X_s \ell\bar\nu decay rate, providing a high-precision calculation with few-percent error that aligns with current experimental data through rigorous chiral and continuum extrapolations.
