Strangeness Enhancement in Proton-Proton Collisions

Abstract: The analysis for the strange and multi-strange hadrons production is presented for proton-proton (pp) collisions at $\sqrt{S_{<em>{NN}}} =$ 200 GeV as reported by the PYTHIA 8 event generator simulations. The strangeness enhancement is studied in details at $\sqrt{s</em>{<em>{NN}}} =$ 200 GeV in proton-proton (pp). We preform the transverse momentum distributions for high and low multiplicity events of the strange and multi-strange hadrons. Here we present the observation of strangeness enhancement in pp collisions for $K</em>{s}<sup>{+}(u\bar{s})$, $K_{s}<sup>{-}(s\bar{u})$, $\Lambda<sup>{0}(uds)$, $\Xi<sup>{0}(uss)$, $\Xi<sup>{-}(dss)$, $\Omega<sup>{-}(sss)$ production. At the RHIC energy, the strangeness content yield increases with the event multiplicity.
