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

Abstract

In this proceedings, we have presented the invariant yield 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 $\sqrt{s_{NN}}$ = 54.4 GeV at midrapidity ($|y|<0.5$). The second and third-order azimuthal anisotropic flow of the above mentioned particles at $\sqrt{s_{NN}}$ = 27 and 54.4 GeV are also discussed. Some of the important observables such as nuclear modification factor ($R_{CP}$), baryon to meson ratio ($\Omega /\varphi$), transverse momentum dependence of $v_2$ and $v_3$ are measured. The number of constituent quark (NCQ) scaling of $v_2$ and $v_3$ is studied for all these particles.
