Abstract:	We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element \|Vcb\| using the decay B?D??? (?=e,?) based on 711 fb-1 of e+e-? (4S) data recorded by the Belle detector and containing 772�106 BB� pairs. One B meson in the event is fully reconstructed in a hadronic decay mode, while the other, on the signal side, is partially reconstructed from a charged lepton and either a D+ or D0 meson in a total of 23 hadronic decay modes. The isospin-averaged branching fraction of the decay B?D??? is found to be B(B0?D-?+??)=(2.31�0.03(stat)�0.11(syst))%. Analyzing the differential decay rate as a function of the hadronic recoil with the parametrization of Caprini, Lellouch, and Neubert and using the form-factor prediction G(1)=1.0541�0.0083 calculated by FNAL/MILC, we obtain ?EW\|Vcb\|=(40.12�1.34)�10-3, where ?EW is the electroweak correction factor. Alternatively, assuming the model-independent form-factor parametrization of Boyd, Grinstein, and Lebed and using lattice QCD data from the FNAL/MILC and HPQCD collaborations, we find ?EW\|Vcb\|=(41.10�1.14)�10-3. � 2016 American Physical Society.
