Abstract

Using the CLEO-II data set we have searched for the decays B⁰→D^(*)+D^(*)-. We observe one candidate signal event for the decay B⁰→D^*+D^*- with an expected background of 0.022±0.011 events. This yield corresponds to a branching fraction of B(B⁰→D^*+D^*-)=[5.3^+7.1_-3.7(stat)±1.0(syst)]×10^-4 and an upper limit of B(B⁰→D^*+D^*-)<2.2×10^-3 at the 90% C.L. We see no significant excess of signal above the expected background level in the other modes, and we calculate the 90% C.L. upper limits on the branching fractions to be B(B⁰→D^*±D^*∓)<1.8×10^-3 and B(B⁰→D⁺D^-)<1.2×10^-3.

N2 - Using the CLEO-II data set we have searched for the decays B0→D(*)+D(*)-. We observe one candidate signal event for the decay B0→D*+D*- with an expected background of 0.022±0.011 events. This yield corresponds to a branching fraction of B(B0→D*+D*-)=[5.3+7.1-3.7(stat)±1.0(syst)]×10-4 and an upper limit of B(B0→D*+D*-)<2.2×10-3 at the 90% C.L. We see no significant excess of signal above the expected background level in the other modes, and we calculate the 90% C.L. upper limits on the branching fractions to be B(B0→D*±D*∓)<1.8×10-3 and B(B0→D+D-)<1.2×10-3.
