When we consider hadrons – their spectra and their interactions, the strong interactions – we are confronted with one of the most challenging problems in modern theoretical physics. Investigating the strong interactions of hadrons, we see an astonishing mixture of understandable and nonunderstandable phenomena, or observations which are not explained satisfactorily. But there are also problems which have to and can be solved, on which we have to concentrate, creating approaches and corresponding methods. The systematization of mesons and baryons [1] presents us many problems of this type in soft hadron interaction processes.
