Charged Particle Multiplicity  near Mid-rapidity vs Energy

56 & 130 GeV : PRL 85, 3100(2000)

200 GeV : PRL 88, 22302(2002)

Results :

Central

Extrapolation to LHC : E(LHC)=30 E(RHIC)

- KN Saturation Model :

- A + A Fit :

Model prediction :

• no unexpected increase

• 200 GeV AuAu 55% higher than pp

• dN/dh = 650 +/- 35

for AuAu at 200 GeV (6% central)
