Strangeness production in $O+O$ collisions at $\sqrt{s_{\mathrm{NN}}}=7$ TeV using various model approaches

Abstract

We present the predictions of various observables for strange (${\mathrm{K}}_{\mathrm{S}}^0$, $\Lambda$($\overline{\Lambda }$)) and multi-strange hadrons (${\Xi }^{-}$(${\overline{\Xi }}^{+}$), $\varphi$, and ${\Omega }^{-}$(${\overline{\Omega }}^{+}$)) using the recently updated 3+1D hydrodynamics-based EPOS4 framework and AMPT model. In this study, we report the transverse momentum ($p_{\mathrm{T}}$) spectra, particle yields ($\mathrm{d}N/\mathrm{d}y$), and $p_{\mathrm{T}}$ integrated yield ratios relative to pions for $O+O$ collisions at $\sqrt{s_{\mathrm{NN}}}=7$~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 ($p+p$ and $p+Pb$) and large ($Pb+Pb$) collision systems.
