Description
A systematic study was made of the electric dipole moment (EDM) of neutron Dn in various models of CP violation. It was found that in the standard KM model with 3 families the neutron EDM is in the range 1.4x10-33≤ Dn ≤ 1.6x10-31 ecm; that the two Higgs doublet model has approximately the same value of Dn as the standard model; that Dn in the Weinberg model is predicted to satisfy Dn> 10-25 ecm; that in a class of left-right symmetric models Dn is of the order of 10-26-11 ecm; that in supersymmetric models Dn is of the order 10-22φ ecm with φ being the possible phase difference of the phases of gluino mass and the gluino-quark-smark mixing matrix and that the strong CP parameter θ is found to be θ < 10-9, using the present experimental limit that Dn < 2.6 x 10-25 ecm with 90% confidence. 65 refs., 10 figs
