Abstract
We have searched for the lepton-number violating processes with and , using a sample of million events collected with the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We find no evidence for these decays and place 90%-confidence-level upper limits on their branching fractions , , , and .
