Abstract
A dynamical symmetry breaking model of electroweak interactions is investigated based on strongly interacting fermions. Vector-like fermions of different representations of the weak SU(2) 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 effective Lagrangian of a doublet scalar field composed of the new fermion fields. Gap equations are derived and the conditions for finding a symmetry breaking solution are presented. The parameters of the model are constrained further by perturbative unitarity. The oblique electroweak corrections only slightly constrain the model. It is shown that the new charged fermions are produced at the next linear colliders in large number and the cross section for the LHC is presented.
