    • and articles cited in Ref. 5. These calculations generally indicate that the neutron electric dipole moment inferred from the rate of KL-> 2 pi is close to or a little larger than the present experimental bound, but that the predicted values become considerably larger if the strange-quark operator s bar γ5σ μν s is assumed to have an appreciable expectation value in the neutron.

    • The model of Ref. 2 left it an open question whether CP conservation is broken spontaneously, or intrinsically in the scalar polynomial. A spontaneous breaking of CP could produce troublesome cosmological domain boundaries;

    • Note that for two doublets, the Fermi coupling constant GF is given by sqrt 2 GF= ( | λ1|2+ | λ2|2)-1, so with maximum CP violation, both ImZ2 and ReZ2 would be expected to be of order unity, or (if | λ1| >> | λ 2|) greater.
