Constraining the initial temperature and shear viscosity in a hybrid hydrodynamic model of √s_NN=200 GeV Au+Au collisions using pion spectra, elliptic flow, and femtoscopic radii

A new framework for evaluating hydrodynamic models of relativistic heavy ion collisions has been developed. This framework, a comprehensive heavy ion model evaluation and reporting algorithm (CHIMERA) has been implemented by augmenting UVH 2+1D viscous hydrodynamic model with eccentricity fluctuations, pre-equilibrium flow, and the ultrarelativistic quantum molecular dynamic (UrQMD) hadronic cascade. A range of initial temperatures and shear viscosity to entropy ratios were evaluated for four initial profiles, N_part and N_coll scaling with and without pre-equilibrium flow. The model results were compared to pion spectra, elliptic flow, and femtoscopic radii from 200 GeV Au+Au collisions for the 0-20% centrality range. Two sets of initial density profiles, N_part scaling with pre-equilibrium flow and N _coll scaling without were shown to provide a consistent description of all three measurements.
