The First Moment of Azimuthal Anisotropy in Nuclear Collisions from AGS to LHC Energies

Figure 2

(a) Charged particle as a function of for 0–40% central Au+Au collisions at , 62.4, 130, and 200 GeV, measured by PHOBOS at RHIC [42]. (b) Comparison of charged particle versus at RHIC [44] and LHC [53] energies. Note that all the RHIC data points are divided by 10 in order to be plotted on a common scale with LHC results.
