Abstract

We apply the three conditions of the Glashow-Weinberg extension of the GIM mechanism for the absence of order G(F) and alpha G(F) flavor-changing neutral currents to the SU(3)(L) x U(1)(x) models of electroweak interactions. We find that these currents can be suppressed without fine-tuning of the parameters, and we obtain lower and upper bounds on the mass of the second neutral gauge boson.
