摘要：We present a study to examine the sensitivity of a future collider to the anomalous top flavour-changing neutral current (FCNC) to the gluon. To separate signal from background a multivariate analysis is performed on top quark pair and background events, where one top quark is considered to follow the dominant standard model (SM) decay, , and the other top decays through FCNC, , where is a - or a -quark. The analysis of fully hadronic FCNC decay of the pair is also presented. The 95% confidence level limits on the top quark anomalous couplings are obtained for different values of the center-of-mass energies and integrated luminosities.
