Summary 1
Charged Particle Densities
dNch/dh at h?0 per participant
- First look at Au+Au at 200 GeV
- increase in density by 14% compared to 130GeV
- Logarithmic increase with energy from AGS to RHIC
- Npart evolution stronger then linear, indicates increasing
contributions from hard processes
dNch/dh in 4p
- Additional particle production concentrated
near h?0 for central events
- Decreasing width with increasing centrality
- On average 4200 particles in central collisions at 130GeV
