Top quark FCNC decays and productions at LHC in littlest Higgs model with T-parity

Han,X; Wang,L; Yang,JM
Subjects:

In the littlest Higgs model with T-parity (LHT) the newly introduced mirror quarks have flavor-changing couplings with the Standard Model (SM) quarks and may enhance the flavor-changing neutral-current (FCNC) top quark interactions which are extremely sup

Top quark three-body decays in R-violating MSSM

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

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

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

Wang,W; Xiong,Z; Yang,JM; Yu,L
Subjects:

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

Dark matter and Higgs phenomenology predicted by left-right twin Higgs model in light of CDMS II results

Wang,L; Yang,JM
Subjects:

The left-right twin Higgs model predicts a light stable scalar \hat{S}, which is a candidate for WIMP dark matter. We study its scattering on nucleon and find that the cross section is below the CDMS II upper bound but can reach the SuperCDMS sensitivity.

Dark matter in the MSSM and its singlet extension

Yang,J
Subjects:

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
Subjects:

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

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
Subjects:

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

Top quark forward-backward asymmetry, FCNC decays and like-sign pair production as a joint probe of new physics

Cao,J; Wang,L; Wu,L; Yang,JM
Subjects:

The anomaly of the top quark forward-backward asymmetry AtFBAFBtA^t_{FB} observed at the Tevatron can be explained by the t-channel exchange of a neutral gauge boson (Z') which has sizable flavor changing coupling for top and up quarks. This gauge boson c

SUSY Dark Matter In Light Of CDMS/XENON Limits

Yang,JM
Subjects:

In this talk we briefly review the current CDMS/XENON constraints on the neutralino dark matter in three popular supersymmetric models: the minimal (MSSM), the next-to-minimal (NMSSM) and the nearly minimal (nMSSM). The constraints from the dark matter re

Light dark matter in NMSSM and implication on Higgs phenomenology

Cao,J; Hikasa,K; Wang,W; Yang,JM; Hikasa,K; Wang,W; Yang,JM
Subjects:

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
