Spacetime as the Manifold of the Internal Symmetry Orbits in the External Symmetries

Abstract

Interactions and particles in the standard model are characterized by the action of internal and external symmetry groups. The four symmetry regimes involved are related to each other in the context of induced group representations. In addition to Wigner’s induced representations of external Poincaré group operations, parametrized by energy-momenta, and the… (More)
