INCLUSIVE WEAK RADIATIVE AND SEMILETPTONIC B DECAY

Abstract

Inclusive weak radiative and semileptonic B decays play a very important role. They are used to determine the weak mixing angles Vcb, and Vub. Furthermore the weak radiative decays provide an important constraint on extensions of the standard model, in particular low energy supersymmetry. I review the theoretical understanding of these processes with particular emphasis on the seminal work of Patrick O'Donnell.
