An Extraction of Vcb from the Semi-Leptonic B->D* Decay

Abstract

We present an extraction of Vcb from a lattice calculation of the B->D* decay matrix elements. We obtain |Vcb| \sqrt{ \frac{ \tauB }{ 1.49 ps } } = 0.037^{+3 \ +5}_{-3 \ -5} from a single parameter fit to the new CLEO data. Email nmh@uk.ac.ed.ph.th
