Abstract：
We calculated the Pseudo Goldstone boson correction to e ⁺e ^－→tc process at the energy √s=500GeV in topcolor-assisted technicolor model. We find that the total contribution is larger than the standard model results by as much as 1 to 2 orders,i.e.the production cross section σ(e ⁺e ^－→tc) can be as large as 10 ^－37cm ²within the considered parameter space. So It may be observable at future e ⁺e ^－collider.
