【 摘 要 】

Searches for flavor changing neutral currents (FCNC) in top production and decay using data collected by the Compact Muon Solenoid (CMS) experiment at √s = 7 and 8 TeV corresponding to an integrated luminosity of around 5 fb-1and 20 fb-1are presented. FCNC searches are conducted to probe tqZ, tqγ, tqH, and tgq interactions in various channels. There is no excess of signal observed in the data. The upper limit of B(t→uγ)
