  An electroweak model in which the masses of the W and Z bosons and the
fermions are generated by quantum loop graphs through a symmetry breaking is
investigated. The model is based on a regularized quantum field theory in which
the quantum loop graphs are finite to all orders of perturbation theory and the
massless theory is gauge invariant, Poincare invariant, and unitary. The
breaking of the electroweak symmetry SU(2) X U(1) is achieved without a Higgs
particle. A fundamental energy scale of ~542 GeV (not to be confused with a
naive cutoff) enters the theory through the regularization of the Feynman loop
diagrams. The theory yields a prediction for the W mass that is accurate to
about 0.5% without radiative corrections. The scattering amplitudes for WW ->
WW and e+e- -> WW processes do not violate unitarity at high energies due to
the suppression of the amplitudes by the running of the coupling constants at
vertices.
