Strangeness Enhancement in Proton-Proton Collisions at the RHIC Energy

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, ${\mathrm{\Lambda }}^0(uds)$ baryon and for multi-strange baryons ${\mathrm{\Xi }}^0(uss)$, ${\mathrm{\Xi }}^{-}(dss)$ and ${\mathrm{\Omega }}^{-}(sss)$ 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.
