Abstract

At the LHC, it will be possible to investigate scenarios for physics beyond the Standard Model in detail. We present precise total and differential cross section predictions, based on Prospino2.0 and SMadGraph. We also show to what degree the structure of the weak--scale supersymmetric Lagrangean can be studied, based on LHC data alone or based on combined LHC and linear collider. Using Sfitter we correctly take into account experimental and theoretical errors. We make the case that a proper treatment of the error propagation is crucial for any analysis of this kind.
