Multiplicity dependence of (multi-) strange hadrons in oxygen-oxygen collisions at s₍₍~=~7 TeV using EPOS4 and AMPT

LHC is anticipated to collect data from oxygen-oxygen (O+O) collisions at center-of-mass energy s₍₍~=~7 TeV to further investigate the particle production mechanisms. In the present work, we report on the predictions of transverse momentum (p ₓ-spectra), dN/dy, yield ratios relative to pions, p ₓ-differential ratios of (multi-) strange hadrons in O+O collisions at s₍₍~=~7 TeV using EPOS4 and AMPT models. Both models differ fundamentally, EPOS4 incorporates a QGP phase, while AMPT focuses on pre-formed hadron interactions. We observed that AMPT qualitatively fails to predict strangeness enhancement in O+O collisions, while EPOS4 predicts a significant enhancement. We also observed the hints of stronger radial flow in EPOS4 compared to AMPT in O+O collisions at s₍₍~=~7 TeV. AMPT incorporates some flow effects, but EPOS4's implementation of full hydrodynamic flow appears to be significantly more effective in reproducing the experimental data. Both models interestingly predict the final state multiplicity overlap with pp, p+Pb, and Pb+Pb collisions. The upcoming data on O+O collisions at the LHC is expected to play a crucial role both, constraining the model parameters and significantly refining our understanding of these theoretical models.
