Abstract

We explore the effects of extra neutral gauge bosons involved in the supersymmetric (Formula presented) model on the spin configuration of the top quark pair produced at the polarized (Formula presented) collider. Generic mixing terms are considered including kinetic mixing terms as well as mass mixing. In the off-diagonal spin basis of the standard model, we show that the cross sections for the suppressed spin configurations can be enhanced with the effects of the (Formula presented) boson through the modification of the spin configuration of produced top quark pair enough to be measured in the linear colliders, which provides the way to observe the effects of the (Formula presented) boson and discriminate the pattern of gauge group decomposition. It is pointed out that the kinetic mixing may dilute the effects of mass mixing terms, and we have to perform the combined analysis.
