Аннотация:We present a summary of the recent results obtained with the novel hadron resonance gas model with the multicomponent hard-core repulsion which is extended to describe the mixtures of hadrons and light (anti-, hyper-)nuclei. A very accurate description is obtained for the hadronic and the light nuclei data measured by STAR at the collision energy $\sqrt{{s}_{NN}}=200\,{\rm{GeV}}$ and by ALICE at $\sqrt{{s}_{NN}}=2.76\,{\rm{TeV}}$. The most striking result discussed here is that for the most probable chemical freeze-out scenario for the STAR energy the found parameters allow us to reproduce the values of the experimental ratios S3 and ${\bar{S}}_{3}$ without fitting.
