We incorporate the gauge-group parameters into the particle Standard Model through a non-linear sigma-model Lagrangian. The new Goldstone-like bosons are minimally coupled according to a proper prescription which provides mass terms to the intermediate vector bosons without spoiling gauge invariance.
