Stabilized NMSSM without Domain Walls

Abstract

We reconsider the Next to Minimal Supersymmetric Standard Model (NMSSM) as a natural solution to the $\mu$-problem and show that both the stability and the cosmological domain wall problems are eliminated if we impose a ${\mathcal{Z}}_2$ $R$-symmetry on the non-renormalizable operators.
