ATLAS results are presented on a search for flavor-changing neutral currents (FCNC) in top quark decays. Events are searched for where a pair of top quarks is produced and one decays through the Standard Model t->Wb mode while the other decays through the FCNC mode t->qZ. Leptonic fina...

description ATLAS results are presented on a search for flavor-changing neutral currents (FCNC) in top quark decays. Events are searched for where a pair of top quarks is produced and one decays through the Standard Model t->Wb mode while the other decays through the FCNC mode t->qZ. Leptonic final states are used in which both the W and Z bosons decay leptonically, yielding final states with three leptons and two jets. The observed events are consistent with the expected backgrounds from Drell-Yan and diboson production and a limit on the FCNC branching fraction of top quarks to qZ is set.
