Özet

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.
