Book Description
The ATLAS detector at the Large Hadron Collider is used to search for the lepton flavor violating process Z -> eμ in pp collisions using 20.3 fb^(-1) of data collected at sqrt(s)= 8 TeV. An enhancement in the eμ invariant mass spectrum is searched for at the Z boson mass. The number of Z bosons produced in the data sample is estimated using events of similar topology, Z -> ee and μμ, significantly reducing the systematic uncertainty in the measurement. There is no evidence of an enhancement at the Z boson mass, resulting in an upper limit on the branching fraction, B(Z -> eμ)

Book Description
Abstract: We present a search for the lepton flavor violating decay Z->eu in proton-proton collisions at a center of mass energy of 7 TeV using approximately 3.1 pb−1 of data recorded with the ATLAS detector at the CERN large hadron collider. Candidate events have two isolated high p[tau] leptons (an electron and a muon), no jets, and little missing transverse energy. We observe no events with eu invariant mass above 60 GeV/c2. This demonstrates that we can suppress the eu background to a negligible level and are sensitive to exotic eu production. We set 95% confidence upper limit on the Z->eu branching ratio of 2.0 x 10−4.

Book Description
We use the ATLAS detector at the Large Hadron Collider to search for the lepton flavor violating process Z→e[mu] in pp collisions using 20.3 fb-1 of data collected at √s=8 TeV. An enhancement in the e[mu] invariant mass spectrum is searched for at the Z-boson mass. The number of Z bosons produced in the data sample is estimated using events of similar topology, Z→ee and [mu][mu], significantly reducing the systematic uncertainty in the measurement. In conclusion, there is no evidence of an enhancement at the Z-boson mass, resulting in an upper limit on the branching fraction, B(Z→e[mu])

Book Description
A search for the lepton-flavor-violating decay of the tau into three charged leptons has been performed using 91.5 fb−1 of data collected at an ee− 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 10−7 at 90% confidence level.
