Signatures of the neutral top-pion in $e\gamma$ collisions

Abstract

We calculate the contributions of the neutral top-pion ${\pi }_t^0$ to the process $e^{-}\gamma \to e^{-}\bar{t}c$ in the framework of topcolor-assisted technicolor(TC2) models and discuss the possible of detecting ${\pi }_t^0$ at the high energy linear $e^{+}{e}^{-}$ collider(LC). Our results show that ${\pi }_t^0$ can give significant contributions to this process. With reasonable values of the parameters in TC2 models, the cross section $\sigma$ can reach 0.19 fb which may be detected at the $e\gamma$ collisions based on the future LC experiments.
