The Standard model of electro-weak interactions is derived from a Nambu, Jona-Lasinio type four-fermion interaction, which is assumed to result from a more basic theory valid above a very high scale {Lambda}. The masses of the gauge bosons and the Higgs are then produced by dynamical symmetry breaking of the Nambu model at an intermediate scale {mu}, and are evolved back to experimental energies via the renormalisation group equations of the Standard model. The weak angle sin{sup 2} ({theta}{sub W}) is predicted to be 3/8 at the scale {mu}, as in grand unified theories, and is evolved back to the experimental value at scale M{sub W}, thus determining {mu} {approximately}10{sup 13}GeV. Predictions for the ratios of the masses of the gauge and the Higgs bosons to the top quark mass, at experimental energies, are also obtained.
