Strange quark collectivity of $\varphi$ meson at RHIC

Abstract

Based on A Multi-Phase Transport model, the elliptic flow $v_2$ of $\varphi$ mesons which is reconstructed from $K^{+}{K}^{-}$ at the Relativistic Heavy Ion Collider (RHIC) energy has been studied. The results show that reconstructed $v_2$ of $\varphi$ meson can keep the earlier information before $\varphi$ decays and it seems to obey the number of constituent quark scaling as other mesons and baryons. This result indicates that the $\varphi$ $v_2$ mostly reflects the parton level collectivity developed during the early stage of the collisions and the strange and light up/down quarks have similar collectivity properties before the hadronization.
