Scientific paper

The production and decay of supersymmetric particles is presented. The dependence of the hadro-production cross section for weakly and strongly interacting yields an improvement of derived mass bounds or the measurement of the masses, respectively, of neutralinos/charginos and stops at the Tevatron and at the LHC. Moreover, the NLO corrections increase the predicted neutralino/chargino cross section by +20% to +40%, nearly independent of the mass of the particles. The consistent treatment as well as the phenomenological implications of scalar top mixing are presented. The correction to the stop production cross sections, depending on the fraction of incoming quarks and gluons, varies between -10% to +40% for an increasing fraction of incoming gluons. The dependence of this cross section on all parameters, except for the masses of the produced particles, is negligible.
