Scientific paper

We consider a gauge-singlet extension of the minimal supergravity motivated (mSuGra) model, which contains only one additional parameter: λ, the Higgs-singlet-Higgs coupling. In NmSuGra the μ-problem is solved and the electroweak fine tuning is reduced compared to mSuGra. First, we identify parameter regions of NmSuGra which are preferred by present experiments. Then, we show that most of these regions are amenable to detection by the combination of the Large Hadron Collider (LHC) and an upgraded Cryogenic Dark Matter Search (CDMS). Regions which are not detectable by the LHC and CDMS are unfavored by the present value of the anomalous magnetic moment of the muon at 99 % confidence level.
