NONPERTURBATIVE YUKAWA COUPLINGS

We have calculated the phase diagram for a chiral Higgs-fermion model on a 4 4 lattice using dynamical fermions. We find two phase transition lines for non-zero values of Yukawa coupling, which may prove useful in finding the continuum limit of the electroweak model.
