Abstract

In these proceedings for CIPANP2015 we present a brief overview of the current status of the theoretical approaches used by our group for the extraction of $|V_{cb}|$ and $|V_{ub}|$ through inclusive semi-leptonic $B$ decays. We discuss the calculations and implications of the recent perturbative corrections to power-suppressed contributions for $|V_{cb}|$, and present an overview of the major sources of theoretical uncertainty for $|V_{ub}|$.
