Description
We discuss the calculation of the inclusive semileptonic decay for the process $B_s \to X_c \, l\nu_l$ using lattice QCD. Such a calculation could be decisive in understanding the CKM matrix puzzle: the long-standing tension between inclusive and exclusive determinations of the CKM matrix element, $V_{cb}$. This talk will be an overview of the calculation using Chebyshev reconstructions. We will go on to explore the steps towards a phenomenological prediction for the inclusive decay rate of the $B_s$. These steps will include analysing systematic effects associated with reconstructions as well as those associated with infinite and continuum limits.
