We present a search for flavor changing neutral currents in decays of top quarks. The analysis is based on a search for (ℓ,ℓ=e,μ) final states using 4.1 fb−1 of integrated luminosity of collisions at . 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.
