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
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
This article presents the sensitivity of the ATLAS experiment to the lepton-flavour-violating decays of [tau]2![mu]. A method utilising the production of [tau] leptons via W2!tau][nu] decays is used. This method is applied to the sample of 20.3 fb-1 of pp collision data at a centre-of-mass energy of 8 TeV collected by the ATLAS experiment at the LHC in 2012. Lastly, no event is observed passing the selection criteria, and the observed (expected) upper limit on the [tau] lepton branching fraction into three muons, Br([tau]2![mu]), is 3.76×10-7 (3.94×10-7) at 90 % confidence level.

Book Description
A search for the nonconservation of lepton flavor number in the decay?{sup {+-}} →?{sup {+-}}? has been performed using 2.07 x 108 ee− →?+?− events produced at a center-of-mass energy near 10.58 GeV with the BABAR detector at the PEP-II storage ring. We find no evidence for a signal and set an upper limit on the branching ratio of?(?{sup {+-}} →?{sup {+-}}?)

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

Book Description
This first open access volume of the handbook series contains articles on the standard model of particle physics, both from the theoretical and experimental perspective. It also covers related topics, such as heavy-ion physics, neutrino physics and searches for new physics beyond the standard model. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
