Inclusive semileptonic Ds Xs decays from lattice QCD: continuum and chiral extrapolation
Abstract
We present results for the inclusive semileptonic Ds Xs decay rate from lattice QCD. Chiral and continuum extrapolations are performed using gauge ensembles generated with 2+1 flavours of M\"obius domain-wall fermions. Systematic errors are fully addressed including those from the integral over all possible final states. Our results are in agreement with currently available experimental data, with an error at the few-percent level.
