P stabilizes dark matter and with CP can predict leptonic phases    [PDF]

Ravi Kuchimanchi

We find that spontaneously broken parity (P) or left-right symmetry stabilizes dark matter in a beautiful way. Strong CP problem is solved by additionally imposing CP. Leptonic CP phases vanish in the minimal model, which is an interesting prediction. Experimentally if leptonic CP violation is not found (or is very small) it will be smoking-gun like evidence for the type of models in this work where CP is spontaneously or softly broken and there is a second symmetry such as P, Z2 or Z4. However leptonic CP phases can be present in closely related or non-minimal versions of these models.
