Top quark is currently the heaviest elementary particle found so far. It decays nearly 100% into a b quark and a W boson before hadronization. A possible process is to decay into a up-type quark and a Z or other neutral bosons, which is also called flavor-changing neutral currents (FCNC). In this FCNC process one can even look for a possible Z' particle through the top tagged events. We have been performing related studies at the CMS experiment. In this talk, we will discuss about the current FCNC searches by the LHC experiments. A prospect will also be covered.
