In this proceedings, the lifetime and yields of Λ3H and Λ4H in Au+Au collisions at √SNN = 3 GeV are presented. The measured yields are compared to measurements at other energies and theoretical models, and the physics implications are discussed. We also report the first observation of the Λ3H and Λ4H directed flow in 5 - 40% centrality. The directed flow of Λ3H and Λ4H are compared with those of the copiously produced particles such as p, Λ, d, t, 3He, and 4He. These results shed light on light hyper-nuclei production in heavy-ion collisions in the high baryon density region.
