Description
Strangeness enhancement in high-energy heavy-ion collisions remains a key signature to identify the formation of Quark-Gluon Plasma (QGP) in such collisions. The study of strange hadrons and resonances may provide valuable information about the strongly interacting matter produced in heavy-ion collisions. In particular, the resonance particles are important because of their shorter lifetime (a few $f\rm m/c$), comparable to the medium lifetime and due to the rescattering and regeneration processes at the freeze-outs, the yields of the resonances may vary w.r.t to the non-resonance particles. Recent studies of small collision systems at the Large Hadron Collider (LHC) show unambiguous similarities for hadron production between high multiplicity $pp$, $pPb$ collisions and $PbPb$ collisions. The strangeness enhancement and ratio of yields of identified hadrons play important role in characterizing the LHC data in different collision systems.
In this contribution, we investigate the strange hadron and resonance yields using a $p$QCD-inspired multiple parton scattering approach-based model, EPOS3 including the hydrodynamical evolution of produced particles. The results of the yield ratios of identified hadrons will be presented for $pp$, $pPb$ and $PbPb$ collisions at various LHC energies, exploiting the model parameters to understand the sensitivity of the microscopic mechanism of hadron production.
