Description

The azimuthal angular correlation between a heavy-flavor meson ($J/ \Psi$ and $D^0$) and a light hadron has been measured firstly by the CMS experiment. The elliptic flow of J/psi from the initial state has been successful described not long ago. We investigate the angular correlation between a open heavy flavor meson and a charged light hadron in the Color Glass Condensate framework. Our results show that open heavy flavor mesons ($D^0$ and B) also have a sizable $v_2$ which has a strong mass dependence. The resulting $v_2$ of $D^0$ coincides with recent CMS data. In addition, our prediction for the $v_2$ of non-prompt D mesons decayed from B mesons perfectly agrees with the recent CMS measurement.
