Abstract：
We have studied a neutral top pion production process e+e-→tπ0t in the topcolor assisted technicolor(TC2)model.The studies show that the production cross section is larger than that of the process e+e-→tH both in the standard model(SM)and in the minimal supersymmetric SM.With peasonable values of the parameters in TC2 models,the cross section can reach 20fb.The neutral top pion π0t may be direct observed via this process.
