Abstract
Effect of the top quark electric dipole coupling and the Z gamma gamma coup ling is studied in the pair production of top quark at a photon collider us ing CP-violating asymmetries. Our results show that with a photon collider of geometrical luminosity of 20 fb(-1) it is possible to put limits of the order of 0.1 on the Z gamma gamma coupling and about 2.5 x 10(-17)e cm on t he top quark electric dipole coupling using these asymmetries.
