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.

Subjects:

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
