Abstract
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 into \( b\overline b \) is strongly reduced. In this case, a second lighter CP-even Higgs boson is potentially also observable at the LHC.
