Abstract

Using 5.2 fb-1 of e⁺e^- annihilation data recorded with the BABAR detector at the PEP-II storage ring while operating on the Y(4S) resonance, a sample of fully reconstructed B⁰ decays in the hadronic modes B⁰ -> D^*-pi⁺ and B⁰ -> D^*-rho⁺ have been reconstructed. In this paper, a study of these events is reported, including preliminary measurements of the absolute branching fractions for these modes, which are found to be B(B⁰ -> D^*-pi⁺) = (2.9+/-0.3+/-0.3) x 10^-3 and B(B⁰ -> D^*-rho⁺) = (11.2+/-1.1+/-2.5) x 10^-3.
