摘要：
The complete next-to-leading order QCD corrections to the scalar top quark pair production via gamma gamma fusion in a parent e(+)e(-) collider are calculated in the Supersymmetric Model. Various origins of QCD corrections are discussed based on precise calculations. We find that the conventional gluonic correction dominates gluino and squark quartic interaction corrections. Moreover, the dependences of the corrections on the masses and the mixing angle of the supersymmetric particles are also investigated. (C) 1998 Elsevier Science B.V.
