Dynamical fermion mass generation in strongly coupled gauge theories with scalar field

Abstract

The lattice gauge models with fermion {chi} and scalar matter {phi} fields, which in the strong coupling phase confine and break dynamically a global chiral symmetry, are reconsidered. In these models fermions exist as neutral bound states of the fundamental fermion and scalar, F={phi}{sup {dagger}}{chi}. Their mass is generated dynamically by a shielded gauge mechanism. The scalar field {phi} induces a second order phase transition. Therefore the mechanism might well exist also in continuum. If so, it could be considered as an alternative to the Higgs mechanism, provided the dynamical properties of chiral gauge theories with fermions and scalars are similar to those of the vector-like model we investigate on the lattice. ((orig.)).
