Two particle correlation analysis is applied to events generated with the NEXSPHERIO hydrodynamic code, starting with fluctuating non-smooth initial conditions (IC). Results show that the non-smoothness in the IC survives the hydro-evolution and can be seen as topological features of the angular correlation function of the particles emerging from the evolving system. A long range correlation is observed in the longitudinal direction and in the","authors_text":"B.M. Tavares, F. Grassi, J. Takahashi, N. Xu, R. Andrade, T. Kodama, W.L.Qian, Y.
