Local scale invariance as a fundamental symmetry of Nature is proposed. This necessitates the existence of a new vector boson associated with local scale invariance. The new boson is referred to as the Weylon. The local gauge action is taken to be that of the Standard Model withSU(3)⊗SU(2)⊗U(1)gauge symmetry. For gravitational interactions, two actions are considered, one linear in curvature and the other quadratic in torsion. In both types of theories breaking of the local gauge and scale invariance is achieved through the usual doublet of scalars and leads to massive vector bosons with the remarkable result that all Higgs degrees of freedom are entirely eliminated. In both models, the Weylon acquires a mass of around1019 GeV.©1997 American Institute of Physics.
