Conformal relativity a theory of mass. Pt. 1

In a series of papers it will be explained how a kinematic theory of mass follows from adopting the conformal group C as basic space-time symmetry group. As an aspect of the group, kinematic masses are bare masses; physical masses are to be calculated from these and interactions. The particle solutions are of two kinds: massless, or massive families consisting of the C-multiplet plus an infinite set of discrete excited mass states. An unexpected consequence of conformal symmetry is the extrapolation of the space-time origin of (some at least) internal symmetries. In particular, C-multiplets provide isospin labels and the free Lagrangians, pure conformal group constructs, possess isospin SU2 invariance as an accidental (''dynamical'') symmetry. New possibilities for gauge theories of interactions are also implied. The new way of handling mass allows gauge bosons of nonzero bare mass (as well as massless ones) without violating gauge invariance. Thus Higgs fields and vacuum broken symmetries are no longer necessary in gauge theory
