Search for lepton-number-violating B + → D − ℓ + ℓ ′ + decays

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...
