Abstract
We present a search for flavor changing neutral currents in decays of top quarks. The analysis is based on a search for tt¯âââ²Î½ââ¯+jets (â,ââ²=e,μ) final states using 4.1 fbâ1 of integrated luminosity of pp¯ collisions at s=1.96 TeV. We extract limits on the branching ratio B(tâZq) (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.
