We report on the study of soft gluon effects in the production of squarks andgluinos at hadron colliders. Close to production threshold, the emission ofsoft gluon results in the appearence of large logarithmic corrections in thetheoretical expressions. In order to resum these corrections atnext-to-leading-logarithmic accuracy appropriate one-loop anomalous dimensionshave to be calculated. We present the calculation of the anomalous dimensionsfor all production channels of squarks and gluinos and provide numericalpredictions for the Tevatron and the LHC.
