Nuclear Scattering at Very High Energies

We discuss the current understanding of nuclear scattering at very high energies. We point out several serious inconsistencies in nowadays models, which provide big problems for any interpretation of data at high energy nuclear collisions. We outline how to develop a fully self-consistent formalism, which in addition uses all the knowledge available from studying electron-positron annihilation and deep inelastic scattering, providing a solid basis for further developments concerning secondary interactions.
