A study of pure multi-strange hadrons production in Pb+Pb collisions at LHC energies using HYDJET++ model

Abstract

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. We have simulated the $p_{T}$-spectra and elliptic flow ($v_{2}$) of $\phi$-meson and $\Omega$-baryons comparing our results with ALICE experimental data and several phenomenological models (HIJING/$B\overline{B}$, VISHNU, EPOS, AMPT, and Krakow) across various centrality intervals. Additionally, 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 $\phi$ and $\Omega$ hadrons production over a wide range of ultra-relativistic collision energies. We also present the particle ratios ($\Omega/\phi$, $\overline{\Omega}^{+}/\Omega^{-}$, $\Omega/\pi$, and $\phi/\pi$), offering insights on the strangeness enhancement and chemical properties of the medium at both LHC collision energies.
