Geometrical CP violation in the N-Higgs-doublet model

Understand

Geometrical CP violation is a particular type of spontaneous CP violation in which the vacuum expectation values have phases which are calculable, i.e.

• stable against the variation of the free parameters of the scalar potential.
• Although originally suggested within a specific version of the three-Higgs-doublet model, it is a generic phenomenon.
• We investigate its viability and characteristic features in models with several Higgs doublets.
