NeXSPheRIO Results on Elliptic-Flow Fluctuations at RHIC

By using the NexSPheRIO code, we study the elliptic-flow fluctuations in Au+Au collisions at 200A GeV. It is shown that, by fixing the parameters of the model to correctly reproduce the charged pseudo-rapidity and the transverse-momentum distributions, reasonable agreement of with data is obtained, both as function of pseudo-rapidity as well as of transverse momentum, for charged particles. Our results on elliptic-flow fluctuations are in good agreement with the recently measured data in experiments.Comment: 12 pages, 6 figures, prepared for the Workshop "Relativistic Nuclear Physics: from Nuclotron to LHC Energies", June 18-22, 2007 (BITP, Kiev, Ukraine
