Abstract
- The elliptic flow v<subscript>2</subscript>, for , , p andin Au+Au collisions at center-of-mass energies , 11.5, 14.5 and 19.6 GeV, is analyzed using a multiphase transport model. A significant difference in the v<subscript>2</subscript>values for p andis observed, and the values of v<subscript>2</subscript>splitting are larger compared withand , and . The difference increases with decreasing the center-of-mass energy. The effect of the quark coalescence mechanism in a multi-phase transport model to the value of elliptic differencebetween p andhas been discussed. The simulation of Au+Au collisions at 14.5 GeV shows that the effect of hadron cascade tois not obvious, and a larger parton-scattering cross section can lead to a larger . [ABSTRACT FROM AUTHOR]
