Elliptic flow of hadrons in Au+Au collisions at sNN p = 7:7; 19:6 and 39 GeV from a multi-phase transport model based on a dynamical quark coalescence mechanism

We present a study of the transverse momentum (p _T) spectra and the differential elliptic flow (v ₂) in a multi-phase transport model based on a dynamical quark coalescence model for Au + Au collisions at and 39 GeV. We have compared our results with the experimental data. The v ₂ of is found to be sensitive to the size parameter for mesons in the model. Our study indicates that the elliptic flow splitting between p and at lower energies may be partly due to quark coalescence in phase space.
