在NMSSM的参数空间中的自然区域可以容纳一个CP-甚至希格斯玻色子的质量约为125 GeV，同时，在双光子通道的增强的横截面倍分支比。这种情况发生在强的单重态-二重态混合的情况下，当125 GeV的希格斯玻色子的部分宽度被强烈减少时。在这种情况下，第二个更轻的CP-甚至希格斯玻色子也可能在LHC中观察到。
A natural region in the parameter space of the NMSSM can accomodate a CP-even Higgs boson with a mass of about 125 GeV and, simultaneously, an enhanced cross section times branching ratio in the di-photon channel. This happens in the case of strong singlet-doublet mixing, when the partial width of a 125 GeV Higgs boson intois strongly reduced. In this case, a second lighter CP-even Higgs boson is potentially also observable at the LHC.
