Abstract

Employing generalized Schiff's transformation on electric dipole moments (EDM) in quantum field theory, we show that the chromoelectric EDM lagrangian density is transformed into the electric EDM term with a new coefficient. Under the new constraint on the EDM operators, the neutron EDM can be described by a unique combination of electric EDM d_f and chromoelectric EDM d_f of quarks. If the special relation of d_f=e_f\over2g_s d_f holds, then the neutron EDM is suppressed significantly.
