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

Figure 14

Beam energy dependence of directed flow slope for protons in 10–40% centrality Au+Au from the STAR experiment, compared with recent hybrid [95] and 3FD [94] model calculations. All the experimental data are from [47] except for one energy point, GeV [90], which should be considered a preliminary measurement.
