A Higgs boson near 125 GeV with enhanced di-photon signal in the NMSSM    [PDF]

Ulrich Ellwanger

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 bb is strongly reduced. In this case, a second lighter CP-even
Higgs boson is potentially also observable at the LHC.
