$\phi$ meson production and partonic collectivity at RHIC
  New results on $\phi$-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 $\phi$ and $\Omega$ and the associated soft particles was simulated. Knowledge about these results are discussed.
