Available in PDF, EPUB and Kindle. Book excerpt: Charged lepton-flavor violating processes are extremely rare in the Standard Model, but they are predicted to occur in several beyond-the-Standard Model theories, including Supersymmetry or models with leptoquarks or compositeness. We present a search for such processes in a sample of 117 x 106 [Upsilon](3S) decays recorded with the BABAR detector. We place upper limits on the branching fractions BF([Upsilon](3S) 2!e{sup {+-}}[tau]{sup {-+}})
