Elliptic and triangular flow of light nuclei in Au+Au collisions in the BES-II energies using the STAR detector

Abstract

Light nuclei might be formed in heavy-ion collisions by the coalescence of produced (anti-)nucleons or transported nucleons. Due to their low binding energies, they are more likely to form at later stages of the hadronic fireball. In this proceedings, we report the transverse momentum and centrality dependence of elliptic ($v_2$) and triangular ($v_3$) flow of $d$, $t$, and ${}^3$He in Au+Au collisions at $\sqrt{s_{NN}}$ = 14.6 -- 54.4 GeV. The mass number scaling of $v_2(p_T)$ and $v_3(p_T)$ of light nuclei is discussed. We also report the comparison of $v_2(p_T)$ and $v_3(p_T)$ of light nuclei with a transport-plus-coalescence model calculation.
