7. An example of important results:
1999: Csernai & Röhrich [Phys.Lett.B458(99)454] observed the “3rd flow component” at SPS energies, not discussed before. It is observable in the directed flow v1. It is a signature of the soft Quark Gluon Plasma.
2004: Five years later, it was first observed at RHIC, and presented now at QM 2004! STAR, PHOBOS & PHENIX have all measured the flow component v1, and have detected the signs of the “3rd flow component”!

Gluon shadowing and the nuclear modification factor in Glauber-Gribov model
The model links shadowing in A+A collisions to diffraction. In the high-energy limit the blobs in the diagrams are approximated by Pomeron exchanges.
Input: data from HERA on diffractive and inclusive cross-sections - effective quark and gluon structure functions of nucleon and Pomeron
Preprint at ICHEP2002

15. OUTLOOK
Theoretical heavy ion physics is very much needed by complex experiments, new fundamental problems, and high level education.
We need in Bergen new permanent staff, with resources to plan for the next years!
