摘要：
Light nuclei and hyper-nuclei are produced in abundance in heavy-ion collisions. The production mechanism of these species in heavy-ion collisions still remains to be understood. In these proceedings, we report the transverse momentum and centrality dependence of elliptic flow (v(2)) of d, t, and He-3 in Au+Au collisions at root s(NN) = 14.6, 19.6, 27, and 54.4 GeV. Mass number scaling of v(2)(p(T)) of light nuclei is shown. We also report the first observation of hyper-nuclei H-3(A) and H-4(A) directed flow (v(1)) in root s(NN) = 3 GeV mid-central (5-40%) Au+Au collisions in the fixed target mode.
