Abstract
We present the results of a search for the rare flavor-changing neutral-current decays (, and , ) and using a sample of decays corresponding to of integrated luminosity collected by the BABAR detector. No significant signal is observed, and we set an upper limit on the isospin and lepton-flavor averaged branching fraction of and a lepton-flavor averaged upper limit of , both at the 90% confidence level. We also report 90% confidence level branching fraction upper limits for the individual modes , , , , , and .
