Description
We perform a model-independent analysis of the possible residual Klein and generalized
CP symmetries associated with arbitrary lepton mixing angles in the case that there
are three light Majorana neutrino species. This approach emphasizes the unique role
of the Majorana phases and provides a useful framework in which to discuss the origin
of the Dirac CP phase in scenarios with spontaneously broken flavor and generalized
CP symmetries. The method is shown to reproduce known examples in the literature
based on tribimaximal and bitrimaximal mixing patterns, and is used to investigate
these issues for the case of a particular (GR1) golden ratio mixing pattern.
