Measurement of the branching fractions of exclusive (B)over-bar -> D-(*)(pi)l(-)(nu)over-bar(l) decays in events with a fully reconstructed b meson

Abstract:

We report a measurement of the branching fractions for B̄→ D(*)(π)-ν̄ decays based on 341.1fb-1 of data collected at the Υ(4S) resonance with the BABAR detector at the SLAC PEP-II e+e- storage rings. Events are tagged by fully reconstructing one of the B mesons in a hadronic decay mode. We obtain B(B-→D0-ν̄)=(2.33±0. 09stat±0.09syst)%, B(B-→D*0-ν̄)=(5.83±0. 15stat±0.30syst)%, B(B̄0→D+-ν̄)=(2.21±0. 11stat±0.12syst)%, B(B̄0→D*+-ν̄)=(5.49±0. 16stat±0.25syst)%, B(B-→D+π - ν̄)=(0.42±0. 06stat±0.03...
