The process $e^{+}{e}^{-}\to \hat{I}½\bar{\hat{I}}½{\hat{I}}^3$ in topcolor-assisted technicolor models

Abstract

In the context of topcolor-assisted technicolor (TC2) models, we consider the process $e^{+}{e}^{-}\to \hat{I}½\bar{\hat{I}}½{\hat{I}}^3$ and calculate the cross section of this process at leading order.It is shown that the extra U(1) gauge boson $Z^{\prime }$ predicted by TC2 models can give significant contributions to the process $e^{+}{e}^{-}\to \hat{I}{½}_{\ddot{I}}„\bar{\hat{I}}{½}_{\ddot{I}}„{\hat{I}}^3$, which may be detected in the future high energy linear $e^{+}{e}^{-}$ collider(LC) experiments.
