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

27 Feb 2020  ·  Nayak Kishora for the STAR Collaboration ·

In this proceeding, we present the new precise directed flow $v_{1}$, measurement of $\pi$, $K$, $p$ and $\phi$ in Au+Au collisions at $\sqrt{s_{\rm NN}}$ = 27, 54.4 GeV and deuteron at $\sqrt{s_{\rm NN}}$ = 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 $\sqrt{s_{\rm NN}}$ = 200 GeV are reported... The elliptic flow $v_{2}$, of identified hadrons ($\pi$, $K$, $p$, $\phi$, $K^{0}_{S}$, $\Lambda$, $\Xi$, $\Omega$) in Au+Au collisions at $\sqrt{s_{\rm NN}}$ = 54.4 GeV are also presented. The results are compared with model calculations to discuss the physics implications. read more
