Experimental constraints on nMSSM and implications on its phenomenology

Cao,J; Logan,HE; Yang,JM

We examine various direct and indirect experimental constraints on the nearly minimal supersymmetric standard model (nMSSM) and obtain the following observations: (i) The combination of current experiments stringently constrains the parameter space, setti

Top quark three-body decays in R-violating MSSM

Heng,Z; Lu,G; Wu,L; Yang,JM

In the minimal supersymmetric standard model the R-parity violating interactions can trigger various exotic three-body decays for the top quark, which may be accessible at the LHC. In this work we examine the R-violating decays t-> c X_1 X_2, which includ

Lepton flavor-changing processes in R-parity violating MSSM: Z ---> l(i) anti-l(j) and gamma gamma ---> l(i) anti-l(j) under new bounds from l(i) ---> l(j) gamma

Cao,J; Wu,L; Yang,JM

We examine the lepton flavor-changing processes in R -parity violating MSSM. First, we update the constraints on the relevant R -violating couplings by using the latest data on the rare decays ? i → ? j γ . We find that the updated constraints are much st

Lepton-Specific Two-Higgs Doublet Model: Experimental Constraints and Implication on Higgs Phenomenology

Cao,J; Wan,P; Wu,L; Yang,JM

We examine various direct and indirect constraints on the lepton-specific two-Higgs doublet model and scrutinize the property of the Higgs bosons in the allowed parameter space. These constraints come from the precision electroweak data, the direct search

Top quark forward-backward asymmetry at the Tevatron: A Comparative study in different new physics models

Cao,J; Heng,Z; Wu,L; Yang,JM

The top quark forward-backward asymmetry A_{FB}^{t} measured at the Tevatron is above the Standard Model prediction by more than 2-sigma deviation, which might be a harbinger for new physics. In this work we examine the new physics contribution to A_{FB}^

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

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

Dark matter in the MSSM and its singlet extension


We briefly review the supersymetric explanation for the cosmic dark matter. Although the neutralino in the minimal supersymmetric model (MSSM), the next-to-minimal supersymmetric model (NMSSM) and the nearly minimal supersymmetric model (nMSSM) can natura

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

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

Rare Z-decay into light CP-odd Higgs bosons: a comparative study in different new physics models

Cao,J; Heng,Z; Yang,JM

Various new physics models predict a light CP-odd Higgs boson (labeled as aaa) and open up new decay modes for Z-boson, such as Z→f?faZ→f?faZ \to \bar{f} f a, Z→aγZ→aγZ\to a\gamma and Z→aaaZ→aaaZ\to aaa, which could be explored at the GigaZ option of the

New physics effects on top quark spin correlation and polarization at the LHC: a comparative study in different models

Cao,J; Wu,L; Yang,JM

Extensions of the Standard Model often predict new chiral interactions for top quark, which will contribute to top quark spin correlation and polarization in tt?tt?t\bar{t} production at the LHC. In this work, under the constraints from the current Tevatr
