CPNonconservation without Elementary Scalar Fields

Dynamically broken gauge theories of electroweak interactions provide a natural mechanism for generating $\mathrm{CP}$ nonconservation. Even if all vacuum angles are unobservable, strong $\mathrm{CP}$ nonconservation is not automatically avoided. In the absence of strong $\mathrm{CP}$ nonconservation, the neutron electric dipole moment is expected to be of order ${10}^{-24\mathrm{}}$e·cm.
