Abstract
The BaBar experiment has recently obtained some important results in the search for new physics in leptonic and lepton flavor violating decays, exploiting the complete datasets collected at the , and energies. In particular, new limits on the ratio , on lepton flavor violating decays of the and , and on decays to three charged leptons or are presented.
