Abstract
We report the measurement of the branching fractions of the rare decays B-0 -> D-s((*)+)pi(-), B-0 -> D-s((*)+)rho(-), and B-0 -> Ds(*)-K(*)+ in a sample of 381x10(6)Upsilon(4S) decays into B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring. We present evidence for the decay B-0 -> Ds-K*+ and the vector-vector decays B-0 -> D-s(*+)rho(-) and B-0 -> Ds*-K*+, as well as the first measurement of the vector meson polarization in these decays. We also determine the ratios of the CKM-suppressed to CKM-favored amplitudes r(D-(*)pi) and r(D-(*)rho) in decays B-0 -> D-(*)+/-pi(-/+) and B-0 -> D-(*)+/-rho(-/+), and comment on the prospects for measuring the CP observable sin(2 beta+gamma).
