Di-jet hadron pair correlation in a hydrodynamical model with jet quenching

In jet quenching, a hard quantum chromodynamics parton, before fragmenting into a jet of hadrons, deposits a fraction of its energy in the medium, leading to suppressed production of high-pT hadrons. Assuming that the deposited energy quickly thermalizes, we simulate the subsequent hydrodynamic evolution of the quark-gluon plasma fluid. Hydrodynamic evolution and subsequent particle emission depend on the jet trajectories. Azimuthal distribution of excess π- due to jet quenching, averaged over all the trajectories, reasonably well reproduces the dihadron correlation as measured by the STAR and PHENIX Collaborations in central and in peripheral Au+Au collisions
