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

Yang,JM; Li,CS
Subjects:

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.

One loop QCD corrections to top quark decay into neutralino and light stop

Li,CS; Oakes,RJ; Yang,JM
Subjects:

We calculate the one-loop QCD corrections to t → t ̃ χ ̃0 using dimensional reduction scheme, including QCD and supersymmetric QCD corrections. The analytic expressions for the corrections to the decay width are given, which can easily be extended to t → χ ̃+j ̃bi. The numerical results show that the correction amounts to more than a 10% reduction in the partial width relative to the tree level result. We also compare the corrections in the no-mixing stop case with those in the mixing stop case.
