Ratio of correlated near-side (|Δφ-π| < π/3) between out-of-plane (|φ-Ψ2|>π/3) and in-plane (|φ-Ψ2|<π/6) π0 triggers in the pT range 11-14 GeV/c, in EMCal-Gamma triggered events in the 30-50% centrality range. JEWEL (without recoils) model comparison is plotted along side for the same centrality range, with initial temperature parameter 590 MeV. zoomed out for easy comparison to other event plane ratios.
This plot compares (as a ratio) the near-side yields in correlations between high pT π0s (11-14 GeV/c, |η|<0.7) and charged hadrons (1.5-17 GeV/c, |η| < 0.9) between two cases for the π0 trigger: in-plane (within π/6 of the 2nd order event plane) and out-of-plane (π/3 or more away from the 2nd order event plane). The correlations have been corrected for π0 impurity, and the contribution due to independent flow of π0s and associated particles has been subtracted.
