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

Abstract

The supersymmetric QCD corrections to top quark pair production by $q\bar{q}$ annihilation in $p\bar{p}$ 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 $t\bar{t}$ 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.
