Available in PDF, EPUB and Kindle. Book excerpt: The authors present a recent BABAR search for lepton flavor violation in tau decays. The search for {tau} {yields} {ell}{ell}{ell} ({ell} = e, {mu}) decays is based on a data sample of 91.6 fb{sup -1}. No signal is found in any of six channels and 90% CL upper limits are set in the range of (1-3) x 10{sup -7}. The search for {tau} {yields} {mu}{gamma} decay is done with a 63 fb{sup -1} data sample. The number of observed events is consistent with expected background level and a preliminary upper limit is set at 2 x 10{sup -6} at 90% CL.
