We present a search for flavor changing neutral currents in decays of top quarks. The analysis is based on a search for t (t) over bar -> l´vl (l) over bar + jets (l, l´= e. mu) final states using 4.1 fb(-1) of integrated luminosity of p (p) over bar collisions at root s = 1.96 TeV. We extract limits on the branching ratio B(t -> Zq) (q = u, c quarks), assuming anomalous tuZ or tcZ couplings. We do not observe any sign of such anomalous coupling and set a limit of B < 3.2% at 95% C.L.
