Conclusions
• PHOBOS has performed the first multiplicity
measurement at RHIC
• Highest particle density measured in man-made collisions
• 70% higher than pp collisions at similar energies
• Strong constraint on model pre/post-dictions
• Upcoming results will answer questions about:
• Centrality dependence (variation with Npart)
• Particle production vs h
• Baryon asymmetry at midrapidity
• Directed and Elliptic flow over full rapidity range
