Abstract

We perform the first search for lepton-number-violating B +→D-+′+ decays, where and ′ stand for e or μ, using 772×106 BB̄ pairs accumulated at the Υ(4S) resonance with the Belle detector at the KEKB e+e- collider. No evidence for these decays has been found. Assuming uniform three-body phase space distributions for the D-+′+ decays, we set the following upper limits on the branching fractions at 90% confidence level: B(B+→D-e+e+)<2. 6×10-6, B(B+→D-e+μ +)<1.8×10-6 and B(B+→D -μ+μ+)<1.1×10-6.
