Top squark mixing effects in the supersymmetric electroweak corrections to top quark production at the Tevatron

Yang,JM; Li,CS

Taking into account the mixing effects between left- and right-handed top-squarks, we calculate the genuine supersymmetric eletroweak correction to top quark pro- duction at the Tevatron in the minimal supersymmetric model. The analytic ex- pressions of the corrections to both the parton level cross section and the total hadronic cross section are presented. Some numerical examples are also given to show the size of the corrections.

Strong supersymmetric quantum effects on top quark production at the Fermilab Tevatron

Li,C; Zhou,H; Zhu,Y; Yang,J

The supersymmetric QCD corrections to top quark pair production by qq ? anni- hilation in pp ? collisions are calculated in the minimal supersymmetric model. We consider effects of the mixing of the scalar top quarks on the corrections to the total tt ?production cross section at the Fermilab Tevatron. We found that such correction is less sensitive to squark mass and gluino mass than in no-mixing case, and in both cases the corrections can exceed 10% even if we consider the recent CDF limit on squark and gluino masses.

Yukawa corrections to top pair production in photon-photon collision

Li,C; Yang,J; Zhu,Y; Zhou,H

The O(αmt 2/mW 2)O(αmt 2/mW 2)O(\alpha m_t~2/m_W~2) Yukawa corrections to top pair production in photon-photon collision are calculated in the standard model (SM), the general two-Higgs-doublet model (2HDM) as well as the minimal supersymmetric model (MSS

Probing top quark decay into light stop in the supersymmetric standard model at the upgraded Tevatron

Hosch,M; Oakes,R; Whisnant,K; Yang,JM; Young,B; Zhang,X

We investigate the possibility of observing the exotic decay mode of the top quark into the lightest stop (t~1t~1\tilde t_1) and neutralino (χ~01χ~10\tilde\chi^0_1) in the minimal supersymmetric standard model with R-parity at the upgraded Tevatron. First

Probing anomalous top quark couplings at e gamma colliders

Cao,J; Wang,J; Yang,JM; Young,B; Zhang,X

We study in the effective Lagrangian approach the possibility of probing anomalous top quark charged current couplings in the single top production at a high energy e\gamma collider. We analyzed all possible dimension-six CP-conserving operators which can

Xiong,Z; Yang,JM

Rare decays B_{s,d}-->mu^+ mu^- are evaluated in technicolor model with scalars. R_b is revisited to constrain the model parameter space. It is found that restriction on f/f' arising from R_b which was not considered in previous studies requires f/f' no l

Probing R-parity Violating Interactions from Top Quark Polarization at LHC

Li,P; Lu,G; Yang,JM; Zhang,H

In minimal supersymmetric standard model the R-parity violating interactions can induce anomalous top pair productions at the LHC through the t-channel process d_R \bar d_R -> t_L \bar t_L by exchanging a slepton or u-channel process d_R \bar d_R -> t_R \

Production of h t anti-t and h t anti-T in littlest Higgs model with T-parity

Wang,L; Wang,W; Yang,JM; Zhang,H

In the littlest Higgs model with T-parity, which predicts a pair of T-even and T-odd partners for the top quark, the top quark interactions are altered with respect to the Standard Model predictions and deviation will manifest in various top quark process

Virtual Effects of Split SUSY in Higgs Productions at Linear Colliders

Wang,F; Wang,W; Xu,F; Yang,JM; Zhang,H

In split supersymmetry the gauginos and higgsinos are the only supersymmetric particles possibly accessible at foreseeable colliders like the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC). In order to account for the cosmic
