Abstract
In high-energy-nuclear collisions, di-hadron correlations are used as a probe to study energy-loss mechanisms of jets in the Quark-Gluon Plasma (QGP). In order to understand the interplay between jet-medium interaction and medium expansion, we measured di-hadron correlations where events were classified by the trigger-hadron's angle with respect to the event plane. We further constrained the collision geometry using event-shape engineering based on the magnitude of the reduced flow vector q(2). This measurement provides new and unique constraints for the dependence of energy loss of jets on in-medium path length and the role of flow.
