摘要：

Production of the (anti)hypertriton nuclei HΛ3 and H¯Λ¯3 in Cu+Cu interactions at sNN=200 GeV is studied in three centrality bins of 0–10%, 10–30%, and 30–60% using the dynamically constrained phase-space coalescence model together with paciae model simulations. They are compared with H3(H¯3) and He3(He¯3) nuclei. It is indicated by the study that the yields of light nuclei and hypernuclei increase rapidly from peripheral to central collisions while their antiparticle-to-particle ratios remain unchanged for different centrality bins.
