Abstract

A reliable determination of the Cabibbo-Kobayashi-Maskawa matrix element |V_cb| is mandatory for precision flavor physics and for the search for CP violating phases from new, heavy particles. In this article, we review the theory of the determination of |V_cb| from inclusive semileptonic B decays. We discuss the available measurements of the semileptonic B branching fraction and other inclusive observables in B decays relevant to the determination of |V_cb|. Finally, we perform a global fit to extract |V_cb| and the b-quark mass m_b.
