| Abstract: | Within the next-to-leading order perturbative QCD description of hard scatterings and using a 2+1 dimension ideal hydrodynamic model, we have studied the effect of initial state fluctuations on jet energy loss in relativistic heavy-ion collisions. We find that a jet loses slightly more energy in the expanding quark-gluon plasma if the latter is described by the hydrodynamic evolution with fluctuating initial conditions compared to the case with smooth initial conditions. A detailed analysis indicates that this is mainly due to the positive correlation between the fluctuation in the production probability of parton jets from initial nucleon-nucleon hard collisions and the fluctuation in the medium density along the path traversed by the jet. This effect is larger in non-central than in central relativistic heavy ion collisions and also for a linear than a quadratic dependence of jet energy loss on its path length in the medium. |
