Title: Search for lepton-number-violating B + D - + ' + decays

Abstract

We perform the first search for lepton-number-violating B+ D -ℓ+ℓ'+ decays, where ℓ and ℓ' stand for e or μ, using 772×106 B ¯B pairs accumulated at the (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 -ℓ+ℓ'+ 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 +) < 1.0 × 10 -6.
