Energy loss of partons traversing a QGP fluid Original Research Article

We analyse the azimuthal correlation function for high pT charged hadrons in Au+Au collisions at the RHIC energy. By using a dynamical model in which hydrodynamics is combined with explicit propagation of high pT partons, we study the effect of the intrinsic transverse momentum of initial partons on the azimuthal back-to-back correlations.
