Abstract

We generalize the geometrical description of CP violation in the standard m odel in terms of a unitarity triangle. For three left-handed Majorana neutr inos CP violation in the lepton sector is determined by three unitarity tri angles. With three additional right-handed neutrinos 15 quadrangles are req uired to characterize CP violation. We show the relation of the unitarity p olygons with physical observables.
