EXTENDING THE STUECKELBERG MODEL FOR SPACETIME SYMMETRIES: COSMOLOGICAL IMPLICATIONS
Abstract
The so-called Stueckelberg transformation is introduced as a prescription of minimal coupling following the procedure of the Utiyama theory, for both internal and spacetime symmetry Lie groups. As a natural example, the theory is applied to the Weyl group and the corresponding gauge gravitational theory is developed. This context appears to be a natural source to account for some sort of dark matter intrinsically related to the gauge-group parameter associated with scale transformations.
