Collision Geometry Scaling of Au+Au pseudorapidity density from sqrt(s_NN) = 19.6 to 200 GeV

Phys. Rev. C70, 021902(R) (2004) 

 

  • Figure 1 - Pseudorapidity regions used in centrality determination 

  • Figure 2 - Midrapidity pseudorapidity density per participant pair as a function of centrality at both energies.

  • Figure 3 - Same as figure 2 but normalized by data for p+p

  • Figure 4 - Ratio of the results for the two energies as a function of centrality, also compared to models.

Data files are available for 19.6 GeV, 200 GeV, and the ratio.
