Interferometry signatures of hydrodynamic sources with fluctuating initial conditions

We investigate the space-time evolution of the hydrodynamic particle-emitting sources with the fluctuating initial conditions generated by Heavy Ion Jet Interaction Generator (HIJING). In order to detect the event-by-event inhomogeneity of the sources, we examine the distribution of the error-inverse-weighted fluctuations, f, between the two-pion Bose-Einstein correlation functions of single and mixed events. We find that the distribution of f becomes wide for the fluctuating initial conditions. The large values of the distribution width and the root-mean-square frms are the signatures of the hydrodynamic particle-emitting sources with the fluctuating initial conditions.
