Physical Review D 67,11 (2003) 112002;
Using 9.1 fb(-1) of e(+)e(-) data collected at the Y(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(*0)rho(-) and (B) over bar (0)-->D(*+)rho(-). The fraction of longitudinal polarization in (B) over bar (0)-->D(*+)rho(-) is found to be consistent with that in (B) over bar (0)-->D(*+)l(-)(ν) over bar at q(2)=M-rho(2), 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.
