AbstractBased on a multiphase transport model, we have studied the elliptic flow v(2) of phi mesons from the reconstructed K(+)K(-) decay channel at the top Relativistic Heavy Ion Collider energy at Brookhaven National Laboratory. The dependences of v(2) on transverse momentum p(T) and collision centrality are presented and the rescattering effect of phi mesons in the hadronic phase is also investigated. The results show that experimental measurement of v(2) for phi mesons can retain the early collision information before the phi decays and that the phi v(2) value obeys the constituent quark number scaling that has been observed for other mesons and baryons. Our study indicates that the phi v(2) mostly reflects partonic-level collectivity developed during the early stage of the nucleus-nucleus collision and the strange and light up/down quarks have developed similar angular anistropy properties at the hadronization.
