Research of bb-bar production in the topcolor assisted technicolor model

In the framework of topcolor assisted technicolor (TC2) model, the authors calculate the contributions of cross section from the pseudo Goldstone bosons and new gauge bosons to e+e-→bb-bar. The authors find that, within reasonable ranges of the parameters, the corrections arising from technipions and new gauge bosons are negligibly small; and the top pions afford dominate contribution, the maximum cross section corrections can reach 43% with the c.m. energy √s=500 GeV; whereas in case of √s=1500 GeV, the maximum cross section relative corrections is only 3.1%. It might open a window to detect topcolor assisted technicolor model in the experiment of next generation linear collider. (authors)
