Study of the ATLAS sensitivity to FCNC decays in single top events

The ATLAS experiment sensitivity to Flavour Changing Neutral Currents (FCNC) top quark decays was studied. Different analyses, corresponding to the $t(\bar t) \to q(\bar q) X$ ($X=Z,\gamma$) decay channels are presented. The branching ratio sensitivity to FCNC top quark decays were obtained assuming...

Sumario:The ATLAS experiment sensitivity to Flavour Changing Neutral Currents (FCNC) top quark decays was studied. Different analyses, corresponding to the $t(\bar t) \to q(\bar q) X$ ($X=Z,\gamma$) decay channels are presented. The branching ratio sensitivity to FCNC top quark decays were obtained assuming a $5\sigma$ signal significance and, in the hypothesis of absence of signal, expected limits at 95\% confidence level were derived.
