On Weyl's Extension of the Relativity Principle as a Tool to Unify Fundamental Interactions

Keywords: Weyl's idea, relativity principle, unify fundamental interactions, gravity
The principle of democracy between reference systems which was formulated by Galileo, modified by the special relativity theory and generalised by general relativity could be extended and applied also to reference scales. Basing on this Weyl's idea we review a model that unifies fundamental interactions of elementary particles described by the Standard Model and gravity. Local conformal symmetry is a pivotal feature of this model. The most important phenomenological consequence of this approach is the absence of the dynamical scalar field in the predicted particle spectrum.
