A limit on the fermion masses in a technicolor scenario

Abstract

Recently it has been pointed out that no limits can be put on the scale of fermion mass generation (M) in technicolor models, because the relation between the fermion masses (mf) and M depends on the dimensionality of the interaction responsible for generating the fermion mass. Depending on this dimensionality it may happens that mf does not depend on M at all. We show that exactly in this case mf may reach its largest value, which is almost saturated by the top quark mass. We make few comments on the question of how large can be a dynamically generated fermion mass.
