AbstractIn this work, the relative Underlying event (UE) transverse multiplicity activity classifier ($$R_\mathrm{{T}}$$ R T ) is used to study the strange and multi-strange hadron production in proton-proton collisions. Our study with $$R_\mathrm{{T}}$$ R T would allow to disentangle these particles, which are originating from the soft and hard QCD processes. We have used the PYTHIA 8 Monte-Carlo (MC) with a different implementation of color reconnection and rope hadronization models to demonstrate the proton-proton collisions data at $$\sqrt{s}~$$ s = 13 TeV. The relative production of strange and multi-strange hadrons are discussed extensively in low and high transverse activity regions. In this contribution, the relative strange hadron production is enhanced with increasing $$R_\mathrm{{T}}$$ R T . This enhancement is significant for the strange baryons as compared to mesons. In addition, the particle ratios as a function of $$R_\mathrm{{T}}~$$ R T confirm the baryon enhancement in new Color Reconnection (newCR), whereas the Rope model confirms the baryon enhancement only with strange quark content. Experimental confirmation of such results will provide more insight into the soft physics in the transverse region, which will be useful to investigate various tunes based on hadronization and color reconnection schemes.

We review the methods and results obtained in an analysis of the experimental heavy ion collision research program at nuclear beam energy of 160–200 A GeV. We study strange, and more generally, hadronic particle production experimental data. We discuss present expectations concerning how these observables will perform at other collision energies. We also present the dynamical theory of strangeness production and apply it to show that it agrees with available experimental results. We describe strange hadron production from the baryon-poor quark-gluon phase formed at much higher reaction energies, where the abundance of strange baryons and antibaryons exceeds that of nonstrange baryons and antibaryons.
