Elliptic flow from collision geometry and rescattering

Calculations of elliptic flow based on two initial state models of Au + Au collisions at √ s = 200 GeV/n coupled with a hadronic rescattering calculation are presented. The two initial state models used are a thermal model and a partonic model. Results from these calculations are compared with experiments and it is found that both initial state models give satisfactory representations of elliptic flow measurements, provided that the rescattering is started early enough in the collision process. It is also found that the present hadronic model studies do not show the jet suppression observed experimentally.
