For each case, we give the potential and fi nd various global minima for di ff erent regions of the parameter space of the potential. Using CP-odd basis Invariants that indicate the presence of Spontaneous CP Violation we separate the VEVs into those that do or do not violate CP. In cases where CP is preserved we reveal a CP symmetry of the potential that is preserved by those VEVs, otherwise we display a non-zero CP-odd Invariant. Finally we identify interesting cases where there is Spontaneous Geometrical CP Violation in which the VEVs have geometrical phases.", optnote="WOS:000416354700001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3383), last updated on Fri, 08 Dec 2017 23:35:51 +0000", issn="1029-8479", doi="10.1007/JHEP11(2017)136", opturl="http://arxiv.org/abs/1706.07606", opturl="https://doi.org/10.1007/JHEP11(2017)136", archivePrefix="arXiv", eprint="1706.07606", language="English" }
