Probing the Top Quark Flavour-Changing Neutral Current at a Future Electron-Positron Collider

Table 1

The number of events before and after the kinematical cuts for signal and background at a center-of-mass energy of 0.5 TeV and with 100  integrated luminosity of data for semileptonic and full hadronic top quarks decays (both tops decay anomalously). The -tagging efficiencies have been included and for the signal we have set = 0.02 TeV⁻¹.
