Abstract

We present a study of resonances in exclusive decays of B mesons to (D) over bar (DK)-D-(*)-K-(*). We report the observation of the decays B ->(D) over bar D-(*)(s1)+(2536) where the D-s1(+)(2536) is reconstructed in the (DK+)-K-*0 and (D*+KS0) decay channels. We report also the observation of the decays B ->psi(3770)K where the psi(3770) decays to (D) over bar D-0(0) and D-D+. In addition, we present the observation of an enhancement for the (D) over bar D-*0(0) invariant mass in the decays B ->(D) over bar (DK)-D-*0-K-0, at a mass of (3875.1(-0.5)(+0.7)+/- 0.5) MeV/c(2) with a width of (3.0(-1.4)(+1.9)+/- 0.9) MeV (the first errors are statistical and the second are systematic). Branching fractions and spin studies are shown for the three resonances. The results are based on 347 fb(-1) of data collected with the BABAR detector at the PEP-II B factory.
