Duality in inclusive semileptonic heavy quark decay
Journal Article
·
OSTI ID:755838
The author identifies a source of Lambda{sub QCD}/m{sub Q} corrections to the assumption of quark-hadron duality in the application of heavy quark methods to inclusive heavy quark semileptonic decays Q {r_arrow} ql{anti {nu}}{sub l}. 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 V{sub cb}.
