Predictions for Identified Hadron (π^±, K^± and p(p̄)) Production and Collective Dynamics in Oxygen-Oxygen Collisions at √sNN= 7 TeV with EPOS4, AMPT-SM, and Angantyr in Pythia 8

We study the dynamics of identified hadrons (π^±, K^± and p(p̄)) production in $O+O$ collisions at √sNN = 7TeV using recently updated version of EPOS4, string melting version of A Multi-Phase Transport Model (AMPT-SM) and Angantyr model, incorporated within Pythia 8. We examine the interplay between different mechanisms implemented in these models. Predictions for charged particle multiplicity (dNch/dη), transverse momentum (pT) spectra of identified hadrons, particle yield ($dN/dy$) and mean transverse mass (mT) are presented. To probe the collective behavior of the produced particles, the pT-differential kaons-to-pion and proton-to-pion ratios are studied. While AMPT incorporates some flow effects, EPOS4's implementation of full hydrodynamic flow proves significantly more effective. In contrast, the flow effects in Pythia 8 are substantially weaker compared to the other models. The upcoming $O+O$ data from the LHC will help constrain the parameters of these models.
