摘要：
We reexamine the dipole electric moment of the neutron dn in supersymmetric theories. We reassess the contributions to dn from Weinberg's gluonic operator and the color and electric dipole operators, emphasizing the proper evaluation of their QCD correction factors, and see that dn is a very sensitive probe of these theories. We also give a calculation of the phase that determines dn in realistic models and conclude that the dominant contribution to dn is expected to be due to strong (and not weak) CP-violating effects. © 1990 The American Physical Society.
