Description
The particular azimuthal angular correlation between a heavy meson and a light hadron has first been measured at the LHC recently. In this two particle correlation method, the experimental results show that the elliptic flows for heavy-flavor mesons (J/psi and D^0) are almost as large as those for light hadrons. We investigate the angular correlation between a heavy quarkonium and a charged light hadron in the Color Glass Condensate framework, which indicates that the heavy quarkonium v_2 can be naturally interpreted as an initial state effect. We also predict that the heavy quarkonium Upsilon should have a similar elliptic flow as compared to that of the J/psi, which can be tested in future measurements.
