Abstract

We present the predictions of various observables for strange (K⁰_{\mathrm S}, Λ(Λ)) and multi-strange hadrons (Ξ^-(Ξ⁺), ϕ, and Ω^-(Ω⁺)) using the recently updated 3+1D hydrodynamics-based EPOS4 framework and AMPT model. In this study, we report the transverse momentum (p_{\rm T}) spectra, particle yields (dN/dy), and p_{\rm T} integrated yield ratios relative to pions for O+O collisions at √s_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+p and p+Pb) and large (Pb+Pb) collision systems.
