Abstract
We studied the phase diagram of the lattice formulation of the SU(2)-Higgs model with dynamical fermions. The Yukawa coupling of the fermion fields to the Higgs field is set to zero. The dynamical fermions are included via the hybrid Monte Carlo algorithm. Extensive comparison is made with previous results obtained by Aoki, Lee and Shrock simulating the same model by the Langevin method. We argue that the current status of lattice investigations does not eliminate the possibility of the Abbott-Farhi phase.
