Description
Results on the search for flavor-changing neutral-currents (FCNC) in top-quark production and decay are reported, with data collected with the ATLAS detector at a center-of-mass energy of sqrt(s) = 7 TeV. The single top quark topology is used to place limits on sigma(qg -> t) x B(t -> Wb) (q=u,c). A search is also performed for top-quark pair events, with one top quark decaying through the t->Zq FCNC channel, and the other through the Standard Model dominant mode t->Wb. An upper limit on the t->Zq is set.
