Abstract
We consider the corrections that arise at one loop when integrating out heavy fields in supersymmetric models We show that in type-I see-saw models complex A(N)- and B(N)-terms of the heavy right-handed neutrino give radiative contributions to the neutron EDM as well as new dominant contributions to the electron EDM Type-II and type-III see-saw also predict a pure gauge correction that makes complex the masses of the weak gauginos All the see-saw models can predict observable EDM for the electron and for the neutron in a peculiar ratio (C) 2010 Elsevier BV All rights reservedFile in questo prodotto:
