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

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

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

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.

Dimension-six CP conserving operators of the third family quarks and their effects on collider observables

Whisnant,K; Yang,J; Young,B; Zhang,X

Supersymmetric QCD corrections to single top quark production at the Fermilab Tevatron

Li,C; Oakes,RJ; Yang,J; Zhou,H
Subjects:

We evaluate the supersymmetric QCD corrections to single top quark production via qq?′→tb?qq?′→tb?q \bar q'\to t \bar b at the Fermilab Tevatron in the minimal supersymmetric model. We find that within the allowed range of squark and gluino masses the sup

Huang,T; Yang,J; Young,B; Zhang,X
Subjects:

The dimension-six CP-violating SU_L(2)\times U_Y(1) invariant operators involving the tau lepton are studied. The constraints from the available experimental data on tau dipole moments are derived. Under the current constraints, the induced CP-violating e

We systematically calculate various flavor-changing neutral-current top-quark processes induced by supersymmetry at the Large Hadron Collider, which include five decay modes and six production channels. To reveal the characteristics of these processes, we
