Abstract

The flavor changing neutral current tcV (V=γ,Z) couplings in the production vertex for the process e⁺e^-→ t c or t c in the standard model are investigated. The precise calculations keeping all quark masses non-zero are carried out. The total production cross section is found to be 1.84 × 10^-9 fb at √ s =200 GeV and 0.572 × 10^-9 fb at √ s =500 GeV respectively. The result is much smaller than that given in ref. \citeclwy by a factor of 10^-5.
