Abstract
We calculate the large Yukawa coupling corrections to the top and bottom scalar quark pair production in annihilation within the Minimal Supersymmetric Standard Model. We include the vertex corrections and the corrections to the gauge boson propagator enhanced by large masses. We find the total corrections are quite significant. In some regions of the parameter space the corrections are larger than 10%.
