The field content of the NMSSM is very similar to the MSSM; it differs merely by the addition of a singlet superfield S, which is introduced to address the μ-problem of the MSSM (for an exhaustive review of the NMSSM see e.g. [1]). The superpotential and soft supersymmetry-breaking terms of the Higgs sector are given by
The phenomenology of this model can be easily connected to the simplified models that we have reviewed previously. If we disregard the Higgsinos and singlino (which if heavy are largely irrelevant for Higgs phenomenology) the Higgs sector of the NMSSM is essentially that of a Type II `2HDM + Scalar' model, where we can immediately identify Hd, Hu as H1,H2.
