On Productions of Net-Baryons in Central Au-Au Collisions at RHIC Energies

Figure 2

Rapidity distributions of net-baryons in central Au-Au collisions at (a) 62.4 and (b) 200 GeV. The solid symbols represent the experimental data of the BRAHMS Collaboration [17–19] measured at the RHIC and collected together in [20], and the squares and diamonds are for 0–5% and 0–10% centralities, respectively. The open symbols are reflected from the data around midrapidity. The curves are our calculated results, where the dotted and dashed curves from left to right are the contributions of LT, TC, PC, and LP, respectively, and the solid curves are the sum of the four sources. Arrows indicate the beam rapidities. See text on the discussion of a few net-baryons to extend beyond the beam rapidities.
