Residual effects of heavy sparticles in bottom quark Yukawa coupling: A Comparative study for MSSM and NMSSM

Wang,W; Xiong,Z; Yang,JM
分类:

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

Dark Matter in the Singlet Extension of MSSM: Explanation of Pamela and Implication on Higgs Phenomenology

Wang,W; Xiong,Z; Yang,JM; Yu,L
分类:

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,L
分类:

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

Constraints of dark matter direct detection experiments on the MSSM and implications on LHC Higgs search

Cao,J; Hikasa,K; Wang,W; Yang,JM; Yu,L
分类:

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,JM
分类:

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,JM
分类:

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,LL
分类:

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,JM
分类:

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,S
分类:

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,JM
分类:

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
