Parton--Hadron Duality in B Meson Decays

Abstract

We summarize the current view on Parton-Hadron duality as it applies to B meson decays. It is emphasized that an OPE treatment is essential for properly formulating duality and its limitations. Duality violations are unlikely to become the limiting factor in describing semileptonic B width vis-a-vie higher order corrections. The consistent extraction of the b quark mass from B production and decays provides a striking example of the theoretical control achieved.
