Abstract

We present the theory of inclusive decays of hadrons containing a heavy quark and discuss its most important applications to the decays of B mesons. We also review the theoretical understanding of the hadronic parameters lambda₁ and lambda₂ (or mu_pi² and mu_G²) entering the heavy-quark expansion.
