  "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 $\\sqrt{s_{\\rm{NN}}}=200$ 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 $d$ ($\\bar d$), $^3{He}$ ($^3{\\bar{He}}$) and $_{\\bar\\Lambda}^3H$ ($\\bar{_{\\bar\\Lambda}^3H}$) follows Gaussian distributions. This means that light (anti)nuclei and (anti)hypertriton are primarily produced in the central collisions.",
