Supersymmetric U(1) Gauge Realization of the Dark Scalar Doublet Model of Radiative Neutrino Mass
Abstract
Adding a second scalar doublet (eta+,eta0) and three neutral singlet fermions N1,2,3 to the Standard Model of particle interactions with a new Z2 symmetry, it has been shown that Re(eta0) or Im(eta0) is a good dark-matter candidate and seesaw neutrino masses are generated radiatively. A supersymmetric U(1) gauge extension of this new idea is proposed, which enforces the usual R parity of the Minimal Supersymmetric Standard Model, and allows this new Z2 symmetry to emerge as a discrete remnant.
