Strangeness Enhancement in Proton-Proton Collisions at the RHIC Energy

TL;DR

This paper reports the observation of strangeness enhancement in proton-proton collisions at RHIC energy, suggesting the possible formation of a de-confinement phase similar to quark-gluon plasma, based on simulation data analysis.

Contribution

It provides the first detailed study of strangeness production and enhancement in pp collisions at RHIC energy using PYTHIA 8 simulations, indicating de-confinement signatures.

Findings

Strangeness yield increases with event multiplicity.

Enhanced production of multi-strange baryons observed.

Transverse momentum distributions analyzed for different multiplicity events.

Abstract

Strangeness enhancement is considered as a potential signature for QGP phase transition. Here we claim the observation of strangeness enhancement in proton-proton (pp) collisions at RHIC energy saying the de-confinement phase is reached. The deep study of matter phase transitions and dynamics of strangeness creation has been preformed for $K_{s}^{+}(u\bar{s})$ and $K_{s}^{-}(s\bar{u})$ mesons, $\Lambda^{0}(uds)$ baryon and for multi-strange baryons $\Xi^{0}(uss)$, $\Xi^{-}(dss)$ and $\Omega^{-}(sss)$ production. The analysis of datasets for the strange and multi-strange hadrons production is presented at $\sqrt{s} =$ 200 GeV as reported by the PYTHIA 8 event generator simulations. We preform the transverse momentum distributions of the strange and multi-strange hadrons for high and low multiplicity events. At the RHIC energy and for pp collisions, the strangeness content yield increases with the event multiplicity.
