Lattice calculation of the $D_s\mapsto X\ell {\bar{\nu }}_{\ell }$ inclusive decay rate: an overview

Abstract

In this talks, on behalf of our collaboration we present an overview of our first-principle lattice QCD calculation of the $D_s\mapsto X\ell {\bar{\nu }}_{\ell }$ inclusive decay rate. Here we introduce the theoretical background and focus on the methodological aspects of the calculation. A detailed discussion of our results, including the comparison with the corresponding experimental measurements will soon be presented in a forthcoming publication.
