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⁺(us) and K_s^-(su) mesons, Λ⁰(uds) baryon and for multi-strange baryons Ξ⁰(uss), Ξ^-(dss) and Ω^-(sss) production. The analysis of datasets for the strange and multi-strange hadrons production is presented at √(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.
