Peccei-Quinn NMSSM in the light of 125 GeV Higgs

We study the phenomenological aspect of the PQ invariant extension of NMSSM in view of recent discovery of 125 GeV Higgs boson. The minimal model does not have supersymmetric mass of singlet supermultiplet. This fact results in very light singlino-like LSP. The model is strongly constrained by the Higgs invisible decay and dark matter properties of the LSP, while some constraints can be relieved by late-time entropy production of saxion decay. The collider signal of the model contains multi-jet and h/W/Z plus missing energy, which can be discovered in the early stage of the 14 TeV LHC.
