Corrections to the process e+e-→bb in the topcolor assisted technicolor model

In the framework of the topcolor assisted technicolor model we calculate the contributions from the pseudo Goldstone bosons and new gauge bosons to e+e-→bb. We find that, for reasonable ranges of the parameters, the top pions afford a dominate contribution, the corrections arising from technipions and new gauge bosons are negligibly small, the maximum of the total corrections is 43% with the c.m. energy √(s)=500 GeV; whereas in the case of √(s)=1500 GeV, the maximum of the relative corrections is only 3.1%. It might open a window to detect a topcolor assisted technicolor model in experiment of next generation linear colliders
