Abstract：
We study the production and decay of the neutral top-pion π0t in topcolor-assisted technicolor (TC2) theory. Our results show that, except for the dominant decay modes b, c and gg, the π_t⁰ can also decay into γγ and Zγ modes. It can be significantly produced at high energy linear e⁺e^－ collider (LC) experiments via the processes e⁺e^－→π0t γ and e⁺e^－→Zπ_t⁰. We further calculate the production cross sections of the processes e⁺e^－→γπ_t⁰→γc and e⁺e^－→Zπ_t⁰→Zc. We find that the signatures of the neutral top-pion π_t⁰ can be detected via these processes.
