Abstract

We have used the dynamically constrained phase space coalescence model to investigate the production of light nuclei (antinuclei) based on the 1.134\ifmmode×\else\texttimes\fi10⁷ hadronic final states generated by the parton and hadron cascade (PACIAE) model for the 0--5% most central Au+Au collisions at √s_NN=200 GeV with |y|<1 and p_T<5 acceptances. The STAR data of _\ensuremathΛ³H, _\ensuremathΛ³H, ³He, and ³He yields and ratios are well reproduced by the corresponding PACIAE results. The transverse momentum distribution of ³He (³He) and _\ensuremathΛ³H (_\ensuremathΛ³H) is also given. It turned out that the transverse momentum distribution of light nuclei is close to that of the corresponding antinuclei.
