Azimuthal anisotropy measurement of multi-strange hadrons in Au+Au collision at $\sqrt{s_{NN}}$ = 27 and 54.4 GeV at STAR

Abstract

In these proceedings, we present the second order ($v_2$) and the third order ($v_3$) azimuthal anisotropy measurements of strange and multi-strange hadrons such as $K_S^0$, $\Lambda$, $\bar{\Lambda }$, $\varphi$, ${\Xi }^{-}$, ${\bar{\Xi }}^{+}$, ${\Omega }^{-}$, ${\bar{\Omega }}^{+}$ in Au+Au collisions at $\sqrt{s_{NN}}$ = 27 and 54.4 GeV at STAR. The centrality dependence of $v_2$ and $v_3$ as well as the number of constituent quark scaling (NCQ scaling) for all the particles mentioned above are discussed. The ratio of $v_2$ of $\varphi$ mesons to that of $\bar{p}$ is presented at $\sqrt{s_{NN}}$ = 54.4 GeV which gives a hint of mass ordering violation at low $p_T$.
