Comment on Weinberg's gauge theory ofCPnonconservation

We show that if $\mathrm{CP}$ violation occurs through the exchange of charged Higgs bosons as recently proposed by Weinberg, then $P$ (and hence $\mathrm{CP}$) is also violated through the exchange of neutral Higgs bosons. Whereas $K_L\to 2\pi$ is not affected by this additional interaction, the neutron electric dipole moment is, and its value can be well within experimental limits.
