[en] The phase diagram of lattice SU(2) gauge theory with fundamental representation Higgs fields is probed by l = 1/2 and l = 1 fermions. Quenched calculations of (anti psi psi)/sub l/ show two distinct regions characterized by broken or unbroken chiral symmetry. The location of the boundary between the two regions depends on the representation l of the fermions. For l = 1/2 fermions, we have verified the presence of Nambu-Goldstone bosons (''pions'') in the region where chiral symmetry is broken and have found evidence for massless physical fermions in the chirally symmetric region. 6 refs., 5 figs
