Abstract

Using 9.1 fb^-1 of e⁺e^- data collected at the Upsilon(4S) with the CLEO detector using the Cornell Electron Storage Ring, measurements are reported for both the branching fractions and the helicity amplitudes for the decays B^--->D*⁰rho^- and B⁰-->D*⁺rho^-. The fraction of longitudinal polarization in B⁰-->D*⁺rho ^- is found to be consistent with that in B⁰-- >D*⁺l^-nu^- at q²=M ² _rho, indicating that the factorization approximation works well. The longitudinal polarization in the B^- mode is similar. The measurements also show evidence of nontrivial final-state interaction phases for the helicity amplitudes.
