The search for a supersymmetric version of the standard model is a central task of the Large Hadron Collider. The interpretation of the experimental data requires accurate and flexible theoretical predictions. We present a new calculation of the next-to-leading order supersymmetric-QCD corrections to the production and the decay of supersymmetric particles. In particular, we provide fully differential cross sections in a partonic Monte Carlo program. We will focus our discussion on the production of squarks which then directly decay into the lightest supersymmetric particle and jets. The methods used and some exemplary results will be presented.
