| description | Hypernuclei, which are bound states of nuclei with at least one hyperon, serve as excellent experimental probes for studying the hyperon-nucleon (Y-N) interaction. In these proceedings, the measurements of A=4 hypernuclei (4ΛH and 4ΛHe) production from the RHIC-STAR experiment utilizing the fixed target datasets are presented. The measured yields dN=dy of 4ΛH and 4ΛHe as a function of rapidity are shown from √sNN and 3.5 GeV Au+Au collisions. Additionally, the energy dependencies of the ratio of 4ΛH/Λ and 4ΛHe/Λ are examined to explore isospin effects. The mass dependence of the mean transverse momentum <pT> are also discussed. Furthermore, calculations from PHQMD, thermal model and transport model JAM plus coalescence afterburner are compared to these results and the relevant physics implications are discussed. |
