Neutral top-pion and top-charm production in high energy $e^{+}{e}^{-}$ collisions

Abstract

We calculate the contributions of the neutral top-pion, predicted by topcolor-assisted technicolor (TC2) theory, to top-charm production via the processes $\gamma \gamma ⟶\bar{t}c$ and $e^{+}{e}^{-}⟶\gamma \gamma ⟶\bar{t}c$ at the high energy linear $e^{+}{e}^{-}$ collider (LC) experiments. The cross section is of order $10^{-2}pb$ in most of the parameter space of TC2 theory, which may be detected at the LC experiments. So the process $e^{+}{e}^{-}⟶\bar{t}c$ can be used to detect the signature of TC2 theory.
