Abstract

Deep inelastic scattering of charged leptons on nucleons had lead with the observation of scaling of the structure functions to the quark parton picture of nucleons. With improved accuracy of the measurements and an increased scale of Q2 in the scattering experiments violation of scaling was found giving an important basis for the new strong interaction theory, the Quantum Chromo Dynamics. It seems now that charged lepton nucleon scattering is entering a third phase in the understanding of hadronic interactions by actually testing quantitatively predictions of QCD. The muon beam at the CERN SPS with high intensity and high energy makes it possible to combine high accuracy with a large scale of energy and momentum transfer. Furthermore, not only the behaviour of structure functions can be compared with the theory but also particle production via detected hadrons or additional muons.
