Electric Dipole Moment of the Neutron in a Left-Right-Symmetric Theory ofCPNonconservation

The electric dipole moment of the neutron (${{\mu }_n}^e$) is calculated in the left-right-symmetic theory of Mohapatra and Pati and related to $\mathrm{CP}$-nonconserving parameters of the neutral kaon system, yielding the bound ${{\mu }_n}^e\gtrsim {10}^{-22\mathrm{}}|{\eta }_{+-}-{\eta }_{00}| e·\mathrm{cm}$. Recent measurements of $K_0\to 2\pi$ amplitudes indicate that ${{\mu }_n}^e$ may well be of order ${10}^{-25\mathrm{}}e·\mathrm{cm}$ which is several orders of magnitude larger than the prediction of the Kobayashi-Maskawa model and only a few times smaller than the current experimental limit ${{\mu }_n}^e\left(\exp \right)<\mathrm{}6\mathrm{}\times {10}^{-25\mathrm{}}e·\mathrm{cm}$.
