Centrality dependence of $P_{\rm z,s2}$ averaged for $\Lambda$ and $\overline\Lambda$ in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} =$ 5.02 TeV and its comparison with the RHIC results for Au$-$Au collisions at $\sqrt{s_{\rm NN}} =$ 200 GeV. The model calculations [38] for $\Lambda$ and strange quark for Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} =$ 5.02 TeV using the approach described in Ref. [23] are shown by dash-dotted lines.
