Abstract

The extended models of the standard model with a single Majorana fermion could be realized as the low-energy effective theory of the well-motivated ultraviolet models. We study the electric dipole moments generated by the effective operators which are composed of the Majorana fermion and the standard model Higgs bosons, especially focusing on the renormalization effects of the effective operators. We give the one-loop anomalous dimension of the effective operators from the scale where the operators are generated to the electroweak scale. In this proceedings, we focused on the electric dipole moments from electroweak Majorana fermions, triplet and 5-plet. We found the renormalization effects could give an enhancement factor being of the order of O(10)% for a triplet model and being more than two in a 5-plet fermion model.
