Abstract：
The one-loop contributions of pseudo Goldstone bosons to the flavorchanging decay Z→bs(bs) in the one generation technicolor models(OGTM) and the technicolor model with a massless scalar doublet are calculated. We find that the contributions can strongly cnhance the branching ratio B(Z→bs+bs). So, a more stringent limit on the parameters h. λ can be obtained.
