Description

We report on recent progress in the calculation of inclusive semileptonic decay rates for $D_s$ mesons from lattice QCD. In this talk, we present results on the continuum and chiral extrapolations performed using gauge ensembles generated with 2+1 flavors of Möbius domain-wall fermions. We obtain results that are in agreement with currently available experimental data, with an error at the few-percent level.
