Description
Models of spontaneous CP violation can solve the Strong
CP problem without the need of an anomalous Peccei-Quinn symmetry. In this talk
we review the Nelson-Barr approach, quantifying a peculiar coincidence between
unrelated mass scales that these models must satisfy in order to correctly
reproduce the Standard Model quark masses and CP violation. We investigate the
compatibility between this requirement and the induced radiative corrections to the
neutron electric dipole moment, and with bounds coming from collider, electroweak
and flavor observables.
