1. chinaXiv:201612.00474 [pdf]
Wang,W; Xiong,Z; Yang,JMSubjects:
| If the sparticles are relatively heavy (a few TeV) while the Higgs sector is not so heavy ( mA is not so large), the Higgs boson Yukawa couplings can harbor sizable quantum effects of sparticles and these large residual effects may play a special role in |

Wang,W; Xiong,Z; Yang,JM; Yu,LSubjects:
| As discussed recently by Hooper and Tait, the singlino-like dark matter in the Minimal Supersymmetric Standard Model (MSSM) extended by a singlet Higgs superfield can give a perfect explanation for both the relic density and the Pamela result through the |

SUSY dark matter in light of CDMS II results: a comparative study for different models
Cao,J; Hikasa,K; Wang,W; Yang,JM; Yu,LSubjects:
| We perform a comparative study of the neutralino dark matter scattering on nucleon in three popular supersymmetric models: the minimal (MSSM), the next-to-minimal (NMSSM) and the nearly minimal (nMSSM). First, we give the predictions of the elastic cross |

Cao,J; Hikasa,K; Wang,W; Yang,JM; Yu,LSubjects:
| Assuming the lightest neutralino solely composes the cosmic dark matter, we examine the constraints of the CDMS-II and XENON100 dark matter direct searches on the parameter space of the MSSM Higgs sector. We find that the current CDMS-II/XENON100 limits c |

Light dark matter in NMSSM and implication on Higgs phenomenology
Cao,J; Hikasa,K; Wang,W; Yang,JM; Hikasa,K; Wang,W; Yang,JMSubjects:
| For the experimental search of neutralino dark matter, it is important to know its allowed mass and scattering cross section with the nucleon. In order to figure out how light a neutralino dark matter can be predicted in low energy supersymmetry, we scan |

Split-SUSY dark matter in light of direct detection limits
Cao,J; Wang,W; Yang,JMSubjects:
| We examine the present and future XENON limits on the neutralino dark matter in split supersymmetry (split-SUSY). Through a scan over the parameter space under the current constraints from collider experiments and the WMAP measurement of the dark matter r |

Higgs boson mass in NMSSM with right-handed neutrino
Wang,W; Yang,JM; You,LLSubjects:
| In order to have massive neutrinos, the right-handed neutrino/sneutrino superfield (N ) need to be introduced in supersymmetry. In the framework of NMSSM (the MSSM with a singlet S) such an extension will dynamically lead to a TeV-scale Majorana mass for |

Split supersymmetry under GUT and current dark matter constraints
Wang,F; Wang,W; Yang,JMSubjects:
| We recalculate the two-loop beta functions for three gauge couplings taking into account all low energy threshold corrections in split supersymmetry (split-SUSY) which assumes a very high scalar mass scale MSMSM_S . We find that in split-SUSY with a gaugi |

Singlet extension of the MSSM as a solution to the small cosmological scale anomalies
Wang,F; Wang,W; Yang,JM; Zhou,SSubjects:
| In this work we show that the general singlet extension of the minimal supersymmetric standard model (MSSM) can naturally provide a self-interacting singlino dark matter to solve the small cosmological scale anomalies (a large Sommerfeld enhancement facto |

A split SUSY model from SUSY GUT
Wang,F; Wang,W; Yang,JMSubjects:
| We propose to split the sparticle spectrum from the hierarchy between the GUT scale and the Planck scale. A split supersymmetric model, which gives non-universal gaugino masses, is built with proper high dimensional operators in the framework of SO(10) GU |
