Centrality dependence of light (anti)nuclei and (anti)hypertriton production in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV

Abstract

We have used the dynamically constrained phase space coalescence model to investigate the centrality dependence of light (anti)nuclei and (anti)hypertriton production based on the $6.2\times 10^7$ hadronic final states generated by the PACIAE model in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=200$ GeV in $|y|<1$ and $p_T<5$ acceptances. It turned out that the yields of light (anti)nuclei and (anti)hypertriton strongly depend on the centrality, i.e. their yields decrease rapidly with the increase of centrality bins; but their yield ratios are independent on centrality. These theoretical results are consistent with the STAR and PHENIX data. Furthermore, centrality distribution of $d$ ($\bar{d}$), ${}^{3}He$ (${}^3\overline{He}$) and ${}_{\bar{\Lambda }}^{3}H$ ($\overline{{}_{\stackrel{ˉ}{\Lambda }}^{3}H}$) follows Gaussian distributions. This means that light (anti)nuclei and (anti)hypertriton are primarily produced in the central collisions.
