Measurement of the branching fraction and CP content for the decay B0 → D*+D*-
A signal of 31.8±6.2(stat)±0.4(syst) events in the decay B0→D*+D*- was observed. From the transversity angular distribution of these events, the CP-odd fraction of the final state was also measured. The measurements provide a starting point for measuring time-dependent CP-violating asymmetries in these decays when more data become available.
