Possible Suppression of Neutron EDM

High Energy Physics - Phenomenology 2007-05-23 v1

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 dfd_f and chromoelectric EDM d~f{\tilde d}_f of quarks. If the special relation of df=ef2gsd~f\displaystyle{d_f={e_f\over{2g_s}}{\tilde d}_f} holds, then the neutron EDM is suppressed significantly.
