The significance of the fragmentation region in ultrarelativistic heavy ion collisions

Phys. Rev. Lett. 91, 052303 (2003).

Note that uncertainties listed in data files are systematic only, the statistical errors are negligible.

Data for Figure 1:

•  dN/deta versus eta at 200 GeV for the following centralities

  • 0-6%   6-15%   15-25%   25-35%   35-45%   45-55%

• dN/deta versus eta at 130 GeV for the following centralities

  • 0-6%   6-15%   15-25%   25-35%   35-45%   45-55%

  dN/deta versus eta at 19.6 GeV for the following centralities

  • 0-6%   6-15%   15-25%   25-35%   35-45%

Data for Figure 2 & 3: (Note that the peripheral bin is 35-40% in this data

which has been normalized to Npart.  This is due to an uncertainty in the

determination of Npart for the most peripheral bin at the lowest energy.)

• dN/deta/(Npart/2) versus eta-prime at 200 GeV

  • 0-6%   35-40%

• dN/deta/(Npart/2) versus eta-prime at 130 GeV

  • 0-6%   35-40% 

• dN/deta/(Npart/2) versus eta-prime at 19.6 GeV

  • 0-6%   35-40%

Data for Figure 4: Ratio of peripheral over central at 200, 130, and 19.6.
