Confronting the natural NMSSM with LHC7-8 data

The natural supersymmetry (SUSY) requires that the stop, sbottom, and gluino are around 1 TeV or lighter. By using the direct SUSY search bounds from both the ATLAS and CMS collaborations, we examine the constraints on the natural SUSY in the next to minimal supersymmetric Standard Model. We consider two cases of interpretations for the Higgs boson data: (1) the Standard Model (SM)-like Higgs boson is the lightest CP-even Higgs boson; (2) the SM-like Higgs boson is the second lightest CP-even Higgs boson. We choose 2400 points or so to perform a detailed Monte Carlo simulation analysis, and we observe that the direct SUSY searches at the LHC impose a strong constraint on these light gluino scenarios.Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)8ARTICLEjmli@itp.ac.cn1null8
