First observation of the decay B0 → D*+D*-

Journal article

We have observed four fully reconstructed B0 → D*+D*- candidates in 5.8 × 106 Υ(4S) → BB̄ decays recorded with the CLEO detector. The background is estimated to be 0.31 ± 0.10 events. The probability that the background could produce four or more signal candidates with the observed distribution among D*+ and D*- decay modes is 1.1 × 10-4. The measured decay rate, B(B0 → D*+D*-) = [6.2-2.9+4.0(stat) ± 1.0(syst)] × 10-4, is large enough for this decay mode to be of interest for the measurement ...
