Abstract
Assuming the so-called global duality we argue that it is very likely that local duality needed to obtain results for the hadronic width of heavy meson decays within the 1/m(Q) expansion holds. Hence, if the di screpancy between experiment and the theory concerning charm counting, the semileptonic branching fraction and the lifetimes of b hadrons pe rsist, it may be taken as a hint at some qualitatively new effect in ( nonperturbative) QCD or at new physics.
