Supersymmetry is probably the most attractive theoretical environment
for physics beyond the electroweak scale. Hadron Colliders like the
Tevatron and the LHC have great potential to confirm these ideas. A
large number of production channels and decay chains can be
explored. For several reasons these searches heavily rely on the
theoretical knowledge of the production cross sections, including
higher order corrections. I will give an introducion to the most
relevant search channels including the effect of higher order SUSY-QCD
predictions. Moreover, I will give a brief overview of the methods and
challenges in these computations.
