Hydrodynamic fluctuations and two-point correlations
arXiv:1210.5179 · doi:10.1016/j.nuclphysa.2013.02.190
Abstract
We examine correlations of energy density induced by initial state fluctuations, which are localized in both transverse and longitudinal extent. The hotspots are evolved according to hydrodynamics in a background which includes radial flow. Two-point energy density correlations from these hotspots are computed as a function of the difference in azimuthal angle and rapidity. Such localized perturbations occur naturally in the theory of hydrodynamic fluctuations and may provide insight into some features of the two-particle correlation data from RHIC and the LHC.
