Book Description
This article presents the sensitivity of the ATLAS experiment to the lepton-flavour-violating decays of ????????3?. A method utilising the production of ? leptons via W→?? 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 ? lepton branching fraction into three muons, Br(????????3?), is 3.76×10-7 (3.94×10-7 ) at 90 % confidence level.

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
This thesis presents two analyses of semileptonic b → sl+l− decays using Flavour Changing Neutral Currents (FCNCs) to test for the presence of new physics and lepton flavour universality, and the equality of couplings for different leptons, which on the basis of experimental evidence is assumed to hold in the Standard Model, free from uncertainties as a result of knowledge of the hadronic matrix elements. It also includes the angular analysis of Lambda_b->Lambda mumu decay and the RK* measurement, both of which are first measurements, not yet performed by any other experiment.

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)
