Duality in Inclusive Semileptonic Heavy Quark Decay
Nathan Isgur
Abstract
I identify a source of LambdaQCD/mQ corrections to the assumption of quark-hadron duality in the application of heavy quark methods to inclusive heavy quark semileptonic decays Q->q l nul. These corrections could substantially affect the accuracy of such methods in practical applications and in particular compromise their utility for the extraction of the Cabibbo-Kobayashi-Maskawa matrix element Vcb.
