Standard Model Bosons as Composite Particles
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 lamba.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^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 ~ 10^13 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.
