Non-Linear Realization of Heavy Fermions*

I want to discuss a piece of work which is still going on. Eduardo Flores and Herbert Steger are collaborating with me on this.1 The motivation for us to look into the present problem is as follows: The pattern of masses of the various fermion families seems to indicate that in the fourth family, if in fact there is one more family, the mass of the up-member quark will be very large. In fact, perhaps the top quark in the third family is already heavier than W and Z. If so, our analysis should apply. Let me then generically call this heavy fermion top.
