Energy dependence of light (anti)nuclei and (anti)hypertriton production in the Au-Au collision from sNN =5.0 to 5020 GeV
Abstract
The energy dependence of light (anti)nuclei and (anti)hypertriton production are investigated in central Au-Au collisions from AGS up to LHC energies at midrapidity, using the parton and hadron cascade model (PACIAE) together with the dynamically constrained phase-space coalescence model(DCPC). We find that the yields, yield ratios of the antiparticles to their corresponding particles, the coalescence parameters BA and the strangeness population factor s3 of light (anti)nuclei and (anti)hypertriton strongly depend on the energy. Furthermore, we analyze and discuss the strangeness population factor s3 and the coalescence parameters BA, and find a transition point near by 20 GeV. These results thus suggest the potential usefulness of the s3 and BA of light nuclei production in relativistic heavy-ion collisions as a direct probe of the transition point associated with the QCD critical phenomena. The results from PACIAE+DCPC model are well consistent with experimental data.
