Abstract

We present the predictions of various observables for strange (KS0\mathrm{K}^{0}_{\mathrm S}, Λ\Lambda(Λ\overline{\Lambda})) and multi-strange hadrons (Ξ\Xi^-(Ξ+\overline{\Xi}^+), ϕ\phi, and Ω\Omega^-(Ω+\overline{\Omega}^+)) using the recently updated 3+1D hydrodynamics-based EPOS4 framework and AMPT model. In this study, we report the transverse momentum (pT{p_{\rm T}}) spectra, particle yields (dN/dy{\mathrm{d}N/\mathrm{d}y}), and pT{p_{\rm T}} integrated yield ratios relative to pions for O+OO+O collisions at sNN=7\sqrt{s_{\mathrm{NN}}}=7~TeV. The results reveal that there are indications of stronger radial flow in EPOS4 compared to AMPT. We observe a final state multiplicity overlap with small (p+pp+p and p+Pbp+Pb) and large (Pb+PbPb+Pb) collision systems.
