For the present work, we have used the HYDJET++ model to explore the production of pure multi-strange hadrons in Pb+Pb collisions at √sNN= 2.76 TeV and √sNN= 5.02 TeV collision energies, respectively. \textcolorredWe have performed simulation to investigate transverse momentum (pT) spectra and elliptic flow (v2) 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 (RAA and RCP), 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, Ω+/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√sNN= 5.02 TeV, focusing on RAA, RCP, and particle ratios within the HYDJET++ framework, offering insights into future measurements and particle dynamics in high-energy heavy-ion collisions.
