A SM-like Higgs near 125 GeV in low energy SUSY: a comparative study for MSSM and NMSSM
Cao,J; Heng,Z; Yang,JM; Zhang,Y; Zhu,JSubjects:
| Motivated by the recent LHC hints of a Higgs boson around 125 GeV, we assume a SM-like Higgs with the mass 123-127 GeV and study its implication in low energy SUSY by comparing the MSSM and NMSSM. We consider various experimental constraints at 2-sigma le |

Higgs decay to dark matter in low energy SUSY: is it detectable at the LHC ?
Cao,J; Heng,Z; Yang,JM; Zhu,JSubjects:
| Due to the limited statistics so far accumulated in the Higgs boson search at the LHC, the Higgs boson property has not yet been tightly constrained and it is still allowed for the Higgs boson to decay invisibly to dark matter with a sizable branching rat |

Probing Natural SUSY from Stop Pair Production at the LHC
Cao,J; Han,C; Wu,L; Yang,JM; Zhang,YSubjects:
| We consider the natural supersymmetry scenario in the framework of the R-parity conserving minimal supersymmetric standard model (called natural MSSM) and examine the observability of stop pair production at the LHC. We first scan the parameters of this s |

Status of low energy SUSY models confronted with the LHC 125 GeV Higgs data
Cao,J; Heng,Z; Yang,JM; Zhu,JSubjects:
| Confronted with the LHC data of a Higgs boson around 125 GeV, different models of low energy SUSY show different behaviors: some are favored, some are marginally survived and some are strongly disfavored or excluded. In this note we update our previous sc |

The Z+photon and diphoton decays of the Higgs boson as a joint probe of low energy SUSY models
Cao,J; Wu,L; Wu,P; Yang,JMSubjects:
| In light of recent remarkable progress in Higgs search at the LHC, we study the rare decay process h→Zγh→Zγh \to Z\gamma and show its correlation with the decay h→γγh→γγh \to \gamma\gamma in low energy SUSY models such as CMSSM, MSSM, NMSSM and nMSSM. Und |

Pair Production of a 125 GeV Higgs Boson in MSSM and NMSSM at the LHC
Cao,J; Heng,Z; Shang,L; Wan,P; Yang,JMSubjects:
| In light of the recent LHC Higgs search data, we investigate the pair production of a SM-like Higgs boson around 125GeV in the MSSM and NMSSM. We first scan the parameter space of each model by considering various experimental constraints, and then calcul |

The SM extension with color-octet scalars: diphoton enhancement and global fit of LHC Higgs data
Cao,J; Wan,P; Yang,JM; Zhu,JSubjects:
| In light of the significant progress of the LHC to determine the properties of the Higgs boson, we investigate the capability of the Manohar-Wise model in explaining the Higgs data. This model extends the SM by one family of color-octet and isospin-double |

A light Higgs scalar in the NMSSM confronted with the latest LHC Higgs data
Cao,J; Ding,F; Han,C; Yang,JM; Zhu,JSubjects:
| In the Next-to-Minimal Supersymemtric Standard Model (NMSSM), one of the neutral Higgs scalars (CP-even or CP-odd) may be lighter than half of the SM-like Higgs boson. In this case, the SM-like Higgs boson h can decay into such a light scalar pair and con |

A light SUSY dark matter after CDMS-II, LUX and LHC Higgs data
Cao,J; Han,C; Wu,L; Wu,P; Yang,JMSubjects:
| In SUSY, a light dark matter is usually accompanied by light scalars to achieve the correct relic density, which opens new decay channels of the SM like Higgs boson. Under current experimental constraints including the latest LHC Higgs data and the dark m |

SUSY induced top quark FCNC decay t→cht→cht \rightarrow { ch} after Run I of LHC
Cao,J; Han,C; Wu,L; Yang,JM; Zhang,MSubjects:
| In light of the Higgs discovery and the nonobservation of sparticles at the LHC, we revisit the supersymmetric theory (SUSY) induced top quark flavor-changing decay into the Higgs boson. We perform a scan over the relevant SUSY parameter space by consider |
