Abstract
Recently, a new dynamical symmetry breaking model of electroweak interactions was proposed based on interacting fermions. Two fermions of different SUL(2) representations form a symmetry breaking condensate and generate the lepton and quark masses. The weak gauge bosons get their usual standard model masses from a gauge invariant Lagrangian of a composite doublet scalar field. The new fermion fields become massive by condensation. In this paper the gap equations are given in the linearized (mean field) approximation, and the conditions for symmetry breaking and mass generation are presented. We have shown that there is a region in the parameter space where electroweak symmetry breaking does occur. Perturbative unitarity constrains the self-couplings and the masses of the new fermions; a raw spectrum is given.
