Effective Weinberg--Salam Model From Higher Dimensions
摘要
We consider an 8--dimensional gravitational theory, which possesses a principle fiber bundle structure, with Lorentz--scalar fields coupled to the metric. One of them plays the role of a Higgs field and the other one that of a dilaton field. The effective cosmological constant is interpreted as a Higgs potential. The Yukawa couplings are introduce by hand. The extra dimensions constitute a group manifold. Dirac fields are coupled to the potentials derived from the metric. As result, we obtain an effective four--dimensional theory which contains all couplings of a Weinberg--Salam--Glashow theory in a curved space-time. The masses of the gauge bosons and of the first two fermion families are given by the theory.
