Abstract:
We construct a new minimal extension of the Minimal Supersymmetric Standard Model (MSSM) by promoting the μ\mu-parameter to a singlet superfield. The resulting renormalizable superpotential is enforced by a Z5\mathcal{Z}_5 RR-symmetry which is imposed on the non-renormalizable operators as well. The proposed model provides a natural solution to the μ\mu-problem and is free from phenomenological and cosmological problems.
