Abstract
Within the technicolor framework, realistically large fermion masses can be generated by the driving effect of the higher-energy (ETC) interactions that must be present in these theories. A study of this enhancement effect is reported here, assuming that the ETC interactions arise from a broken gauge theory. The full high energy theory is employed rather than an effective four-fermion description of the ETC interactions. The enhancement effect emerges only when the ETC gauge coupling is near a critical value, but a fermion mass above 100 GeV can be achieved without excessive fine tuning. Furthermore, large mass splittings can be generated by additional small gauge couplings. QCD effects, in particular, can split fermion masses by as much as two orders of magnitude.
