Particle production (total mult.)
lTotal multiplicity per Npart stays constant.
lWNM holds in AA.
lSlight deviation at higher collision energies.
lDeviation from Npart scaling more visible at mid-rapidity.
èHard Process !?
This implies that hard process in primary nucleon-nucleon collisions is important at higher energies.
