Book Description
A search for the lepton-flavor-violating decay of the tau into one charged lepton and two charged hadrons has been performed using 221.4 fb−1 of data collected at an ee− center-of-mass energy around 10.58 GeV with the BABAR detector at the PEP-II storage ring. In all 14 decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (0.7-4.8) x 10−7 at 90% confidence level. All results are preliminary.

Book Description
We present a search for the lepton flavor violating decay modes B{sup ±} → h{sup ±} [tau]l (h = K, [pi]; l = e, [mu]) using the BABAR data sample, which corresponds to 472 million B{bar B} pairs. The search uses events where one B meson is fully reconstructed in one of several hadronic final states. Using the momenta of the reconstructed B, h, and l candidates, we are able to fully determine the [tau] four-momentum. The resulting [tau] candidate mass is our main discriminant against combinatorial background. We see no evidence for B{sup ±} → h{sup ±} [tau]l decays and set a 90% confidence level upper limit on each branching fraction at the level of a few times 10−5.

Book Description
A search for the lepton-flavor-violating decay of the tau into three charged leptons has been performed using 91.5 fb{sup -1} of data collected at an e{sup +}e{sup -} center-of-mass energy of 10.58 GeV with the BABAR detector at the PEP-II storage ring. In all six decay modes considered, the numbers of events found in data are compatible with the background expectations. Upper limits on the branching fractions are set in the range (1-3) x 10{sup -7} at 90% confidence level.

Book Description
The connection of rare decays to supersymmetric grand unification is highlighted, and a review of the status of rare decay experiments is given. Plans for future investigations of processes that violate lepton flavor are discussed. A new result from the MEGA experiment, a search for [mu][sup +] [yields] e[sup +] [gamma], is reported to be B.R.

Book Description
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.

Searches for lepton-flavor-violating decays of a? lepton to a lighter mass lepton and a photon have been performed with the entire dataset of (963 ± 7) x 106? decays collected by the BABAR detector near the?(4S),?(3S) and?(2S) resonances. The searches yield no evidence of signals and they set upper limits on the branching fractions of?(?{sup {+-}} → e{sup {+-}}?)
