On the Lepton-Hadron-collisions

The lepton-hadron collisions are studied from a combined viewpoint of the counting picture, Regge pole phenomenology, sum rules, scaling law and ep-data. The sum rules are used to determine the residues of Regge behavior of the structure functions. It will be shown that in these processes the Pomeron plays only a minor role compared to the vector and the tensor trajectories. The structure functions, their asymptotic behavior, the q2-distribu-The internal structures of hadrons can be studied from a variety of aspects. Among these, investigation by lepton-hadron collisions with considerable momen-tum transfer has well..:known advantages over others. In these processes leptons can be considered as-nearly structureless particles. Thus the lepton vertex i
