Abstract

The complete QCD corrections to the scalar top quark pair production via γγ\gamma \gamma fusion in parent e+ee^{+}e^{-} collider are calculated in the Supersymmetric Model. The various origins of corrections are discussed. We find that the correction due to gluino exchange is smaller than that due to conventional gluonic contribution, and the contribution due to squark quartic interactions is much smaller. Moreover, the dependences of the corrections on the masses and the mixing angle of the supersymmetric particles are also investigated.
