Directed and elliptic flow of identified hadrons, high-$p_{\mathrm{T}}$ charged hadrons and light nuclei in Au+Au collisions at STAR

Abstract

In this proceeding, we present the new precise directed flow $v_1$, measurement of $\pi$, $K$, $p$ and $\varphi$ in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 27, 54.4 GeV and deuteron at $\sqrt{s_{\mathrm{NN}}}$ = 7.7, 11.5, 14.5 and 19.6 GeV. The first measurement of pseudorapidity and centrality dependence of the $v_1$ of high-$p_T$ ($>$5 GeV/$c$) charged hadrons in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV are reported. The elliptic flow $v_2$, of identified hadrons ($\pi$, $K$, $p$, $\varphi$, $K_S^0$, $\Lambda$, $\Xi$, $\Omega$) in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 54.4 GeV are also presented. The results are compared with model calculations to discuss the physics implications.
