We then use the coalescence model to extract from measured \begin{document}$\rm S_3$\end{document} the information about the \begin{document}$\Lambda$\end{document} and nucleon density fluctuations at the kinetic freeze-out of heavy-ion collisions. We also show, using available experimental data, that the yield ratio \begin{document}${{{S}}_{\rm{2}}} = \dfrac{{{{{N}}_{_\Lambda ^3{\rm{H}}}}}}{{{{{N}}_\Lambda }{{{N}}_{{d}}}}}$\end{document} is a more promising observable than \begin{document}$\rm S_3$\end{document} for probing the local baryon-strangeness correlation in the produced medium."> Yield ratio of hypertriton to light nuclei in heavy-ion collisions from <inline-formula><tex-math id="M1-3">\begin{document}${ \sqrt{{ s}_{{NN}}}}$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/3d1a001f-99d7-4ed1-afea-4a8a3d0c96ae/CPC-2020-0211_M1-3.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/3d1a001f-99d7-4ed1-afea-4a8a3d0c96ae/CPC-2020-0211_M1-3.png"/></alternatives></inline-formula> = 4.9 GeV to 2.76 TeV -
