| Figure 4. J/ψ invariant yields for Au + Au collisions as a function of participants pT at different centralities at mid-rapidity. The dashed lines represent the photoproduction and the solid lines represent the hadroproduction. Both lines are without considering the QGP effect. Where the branching ratio ${B}_{{e}^{+}{e}^{-}}\approx 0.06$. The experimental data is from [ |
