On Inclusive B Decays

Abstract

I briefly review the description of inclusive heavy hadron decays based on the inverse heavy quark mass expansion. In particular, I consider the transition $B\to X_u\ell \nu$ and the problem of extracting $V_{ub}$, mainly as far as the separation from the background represented by $b\to c$ modes is concerned. I also discuss how to obtain complementary information from the decay mode $B\to X_s\gamma$.
