abstract
The next-to-minimal supersymmetric extension of the Standard Model (NMSSM) is one of the most favored supersymmetric models. After an introduction to the model, the Higgs sector and the neutralino sector are discussed in detail. Theoretical, experimental, and cosmological constraints are studied. Eventually, the Higgs potential is investigated in the approach of bilinear functions. Emphasis is placed on aspects which are different from the minimal supersymmetric extension.

No statistically significant excess is observed in the search for Higgs decays to two neutral scalars with unequal masses, setting 95% CL upper limits between 0.9 and 36.8 pb depending on mass and decay scenario.
No significant excess observed in search for X → S(bb)H(γγ); 95% CL limits on σ×BR set from 9 fb to 0.06 fb over m_X 170-1000 GeV and m_S 15-500 GeV in 199 fb^{-1} of ATLAS data.
No excess observed in search for Higgs to a1 a1 decays; 95% CL upper limits on branching ratio range 0.007-0.079 for a1 masses 4-15 GeV, excluding >16% in Type III 2HD+S for tan beta >2.
Viable regions in the μNMSSM accommodate the 95 GeV excesses within 2σ and allow heavy CP-even and CP-odd scalars to produce cascades close to current CMS sensitivity.
