Geometric CP violation with extra dimensions.
We discuss how CP symmetry can be broken geometrically through orbifold projections in hidden extra dimensions in the context of brane-bulk models for particle unifications. The CP violation arises from a crash between the geometry of the compactification and the original higher dimensional CP definition. We present toy models to illustrate the idea and suggest ways to incorporate it into more realistic models.
