$\varphi$ meson production and partonic collectivity at RHIC

New results on $\varphi$-meson production and elliptic flow $v_2$ measurements from RHIC 2004 run (Run-IV) have been reviewed. In addition, the di-hadron correlation function between the trigged $\varphi$ and $\mathrm{\Omega }$ and the associated soft particles was simulated. Knowledge about these results are discussed.
