A bstractA 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.

Reconstructing Higgs boson properties from the LHC and Tevatron data (2012, methodology): “Supersymmetric theories that attempt to solve the naturalness problem of the electroweak scale have been stringently constrained by the LHC direct searches as well as by the Higgs boson results [58, 83–113].”
Interpreting LHC Higgs results from natural new physics perspective (2012, background): “A number of partly overlapping papers have recently investigated the 125 GeV Higgs-like excess in the context of composite Higgs [16], supersymmetric Higgs [17–28], and multi-Higgs models [29–32]; see also [33–41].”
