Abstract
Just to get a feeling of possible values of the neutron EDM dn, let us start with a naive estimate as follows:
The first term here, the Compton wavelength of a proton, is a normal scale, that of a nucleon magnetic moment. The second one is the characteristic relative magnitude of weak interactions in hadronic processes (the typical momenta used to construct a dimensionless factor from the Fermi weak interaction constant G are assumed to be comparable to the pion mass mπ). Finally, one may expect that the CP-odd part of the weak interaction is somehow suppressed as compared to the CP-even one. As a natural value of this suppression factor η we take, for the third term, the ratio of the CP-odd and CP-even amplitudes in the decays of K0 mesons.
