Abstract

Comprehensive measurements of light nuclei collectivity provide valuable information for understanding light nuclei production mechanism in heavy-ion collisions.
The

$v_{1}$ and

$v_2$ for deuterons, tritons,

$^3$ He, and

$^4$ He have been measured in Au+Au collisions at

$\sqrt{s_{NN}} = 3$ GeV by the STAR experiment at RHIC.
The data was recorded in fixed-target mode in 2018.
The particle rapidity and transverse momentum dependence of

$v_1$ and

$v_2$ for these particles have been shown. These results are qualitatively consistent with the calculations from the JAM transport model plus nucleon coalescence.
