Abstract We extend the theoretical approach which includes the dynamical and statistical stages for the description of the nucleosynthesis in central collisions of relativistic ions. Previously, this approach was successfully applied to describe experimental data on both normal nuclei and single strange hypernuclei production in the GSI and RHIC-BES energy range. We predict the multiplicities of double strange hypernuclei up to $$^4_{\varLambda \varLambda }$$ Λ Λ 4 H and further intermediate mass nuclei up to $$^8$$ 8 Be for Au+Au central collisions at $$\sqrt{s_{NN}}$$ s NN = 3 GeV, recently explored by the STAR experiments. These nuclei can be identified by the measurement of the correlated particles coming after their decay. Such observations are a crucial test for the nucleosynthesis mechanism.
