Description
In this talk, we present the first fully non-perturbative computation of the decay rate of $D_s\to X\ell\nu$ and of the associated leptonic moments, carried out on state-of-the-art ETMC ensembles at the physical point with four lattice spacings and three volumes. The extraction of the relevant smeared spectral densities from Euclidean four-point correlation functions has been performed with controlled statistical and systematic uncertainties by using the Hansen-Lupo-Tantalo method. Additionally, we present preliminary results of our ongoing calculation of the inclusive semi-leptonic $B_s$ mesons decay rates with focus on some important technical aspects of the calculation.
