| contents | For the present work, we have used the HYDJET++ model to explore the production of pure multi$-$strange hadrons in Pb+Pb collisions at $\sqrt{s_{NN}}$= 2.76 TeV and $\sqrt{s_{NN}}$= 5.02 TeV collision energies, respectively. \textcolor{red}{We have performed simulation to investigate transverse momentum ($p_{T}$) spectra and elliptic flow ($v_{2}$) for $ϕ-$meson and $Ω-$baryons, and compared the results with ALICE experimental data as well as predictions from various phenomenological models across different centrality classes. Furthermore, we have calculated the nuclear modification factors ($R_{AA}$ and $R_{CP}$), which provide a perception of jet quenching phenomena. Hence, our findings enable the study of the energy and system dependence of $ϕ$ and $Ω$ hadrons production over a wide range of ultra-relativistic collision energies. We also present the particle ratios ( $Ω/ϕ$, $\overlineΩ^{+}/Ω^{-}$, $Ω/π$, and $ϕ/π$ ), offering insights into the strangeness enhancement and chemical properties of the medium at both LHC collision energies. Additionally, we explored the predictions for $Ω$-baryon in Pb+Pb collisions at$\sqrt{s_{NN}}$= 5.02 TeV, focusing on $R_{AA}$, $R_{CP}$, and particle ratios within the HYDJET++ framework, offering insights into future measurements and particle dynamics in high-energy heavy-ion collisions. |
