Energy dependence of elliptic flow of $\varphi$-meson in STAR at RHIC

Abstract

We present the measurement of elliptic flow ($v_2$) as a function of transverse momentum ($p_T$) for the $\varphi$-meson in Au+Au collisions at $\sqrt{s_{NN}}$ = 7.7, 11.5 and 39 GeV. At low $p_T$ $\varphi$-meson $v_2$ decreases with decrease in beam energy. The number of constituent quark ($n_{\mathrm{cq}}$) scaled $v_2$ for $\varphi$-meson vs ($m_T-m_0$)/$n_{\mathrm{cq}}$ follows similar trend as other hadrons for $\sqrt{s_{NN}}$= 39 GeV whereas the $n_{\mathrm{cq}}$ scaled $v_2$ for $\varphi$-mesons follows a different trend compared to the other hadrons at $\sqrt{s_{NN}}$= 11.5 GeV.
