Sampling algorithms for lattice field theories face persistent efficiency challenges near the continuum limit, including critical slowing down and, in certain fermionic theories, poor ergodicity across degenerate vacua. Generative diffusion models, recently shown to correspond to stochastic quantization, offer a promising alternative and have been demonstrated for scalar and pure gauge...
Using $N_f = 2+1$ clover fermions across six gauge ensembles generated by the CLQCD collaboration, this work performs simultaneous chiral and continuum extrapolations to determine the electromagnetic properties of charmed mesons, providing the first lattice QCD calculations for the magnetic moments and radii of $D^{\ast+}$ and $D_s^\ast$, and filling the gap for the $D_s^*$ charge radius. The...
We present a first-principles lattice QCD calculation of $\Xi^{-} \to \Lambda $ form factors using $2+1$ flavor gauge ensembles with lattice spacings ranging from 0.06 to 0.1 fm and pion masses between 230 and 340 MeV. This decay provides an independent avenue for determining the Cabibbo--Kobayashi--Maskawa matrix element $|V_{us}|$ in the baryon sector. We determine the full set of vector and...
