摘要：

We calculated the Pseudo-Goldstone bosons (technipions, top-pions) corrections to the cross-section a of the process e(+) e(-) -> (b) over bars in topcolor-assisted multiscale technicolor model at LEP Il energy region. Our results show that, with reasonable value Of the parameters, the cross-section is one order larger than that predicted by the standard model. We discussed the possibility of detecting this rare event at the "B-factory".
