Description
The NMSSM is, for several reasons, an attractive extension of the
Standard Model. One of them is that the gamma ray excess from the
galactic center can be explained with an NMSSM neutralino annihilating
through a light pseudoscalar. Such light dark matter candidate will
lead to invisible Higgs decays at the LHC. Using SFitter we connect
the galactic center excess with the observed dark matter relic density
and invisible Higgs decays. Typical branching ratios of a SM-like
Higgs to NMSSN neutralinos can easily reach 30%.
