Elliptic flow and the high $p_T$ ridge in Au+Au collisions
In this paper we look for a correlations between intermediate $p_T$ particle pairs and the $v_2$ of the remaining low $p_T$ particles. We find that the shape of the flow vector distribution, which is calculated from all low $p_T$ tracks, depends in a non-trivial way on the angular separation between the high $p_T$ particle pairs in the event. Our analysis is based on 200 GeV Au+Au collision measured with the STAR detector.
