摘要：
Various aspects concerning the spectrum and couplings of models with Wilson-Yukawa couplings in the strong Wilson-Yukawa coupling region are discussed. In particular, we note that the renormalized couplings of the fermion vanish in this region. In the symmetric phase away from the symmetry breaking phase transition, the model appears to result in a spectrum of free fermions and glueballs. A slightly modified model results in a gauge fermion theory with vector couplings such as QCD.
