Abstract
We calculate, using computer algebra techniques, a general expression for the one-loop fermion-neutral boson coupling keeping all masses and momenta. The correctness of the result is guaranteed by the application of a number of severe analytic and numerical checks. The result is applied to the calculation of the flavor changing decays of the Z0 in the two Higgs doublet model and to the flavor changing neutral current decays f the fourth generation b′ quark. In the latter case it is found that this process can dominate charged current decays. It is likely that a b′ quark decaying via flavor changing neutral modes could escape detection by conventional searches. © 1989.
