Description
In this work we investigate how the energy and momentum lost by partonic jets in the quark-gluon plasma may affect the final elliptic and triangular flow of low p_T hadrons at RHIC energies. The jets are modeled as external sources in the energy-momentum conservation equations of ideal hydrodynamics, which are solved on an event by event basis. We find that the average integrated elliptic (triangular) flow and the participant eccentricity (triangularity) can become significantly less linearly correlated if the energy loss rate is sufficiently large (dE/dx > 10 GeV/fm). We show that the linear correlation between v_3(p_T < 1 GeV) and v_3(2 < p_T < 3 GeV) is particularly sensitive to the magnitude of dE/dx and, thus, this new observable may be used to distinguish between strong and weak coupling scenarios for the jet energy loss in the QGP.
