Description
LHC is planning to collect oxygen-oxygen ($O+O$) data at a center-of-mass energy of $\sqrt{s_{\mathrm{NN}}}$ = 7 TeV in order to investigate the particle production mechanisms and associated observables. We present predictions of various observables for identified ({$\pi^\pm$}, {$K^\pm$} and {$p(\bar p)$}) and (mutli-)strange hadrons ($\mathrm{K}^{0}_{\mathrm S}$, $\Lambda$($\overline{\Lambda}$), $\Xi^-$($\overline{\Xi}^+$), $\phi$, and $\Omega^-$($\overline{\Omega}^+$)) using the recently updated 3+1D hydrodynamics-based model EPOS4 and two versions the AMPT model. In this study, we report the transverse momentum (${p_{\rm T}}$-spectra), ${\mathrm{d}N/\mathrm{d}y}$, yield ratios relative to pions, ${p_{\rm T}}$-differential ratios for $O+O$ collisions at $\sqrt{s_{\mathrm{NN}}}$ = 7 TeV. It is observed that the AMPT model fails to adequately predict strangeness enhancement in O+O collisions, whereas EPOS4 predicts a significant enhancement. Furthermore, there are indications of stronger radial flow in EPOS4 compared to AMPT. Both models interestingly predict that the final state multiplicity overlaps with pp, p+Pb, and Pb+Pb collisions, reflecting their robustness and consistency in different experimental conditions. The results on anisotropic flow as a function of charged particle multiplicity ($N_{ch}$) will be presented. The anticipated data from $O+O$ collisions at the LHC is set to be instrumental in both fine-tuning the model parameters and deepening our understanding of these theoretical frameworks.
