Resumen	We present a search for flavor changing neutral currents in decays of top quarks. The analysis is based on a search for tt¯ → ℓ′νℓ¯ℓ+jets (ℓ, ℓ′ = e, μ) final states using 4.1 fb−1 of integrated luminosity of pp¯ collisions at ps = 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.
