Relativistic Heavy Ion Collisions help us explore the broad field of Quark Gluon Plasma. At a fundamental level, the partons or the quarks and gluons are involved in producing the final state hadrons, which help understand the phenomenological properties of Quark Gluon Plasma. By relating the parton level collisions to the final state particles, it might be possible to understand both qualitatively and quantitatively the yields of final state hadrons. With the help of the simulation tool Pythia 8, one can make changes to the input process settings i.e. based on 2 -> 2 parton + parton hard scattering and user defined Parton Distribution Function (PDF) set, it may be possible to understand the contribution to production of charged particles as a function of the two options i.e. process settings and the PDF sets. Through the simulations done with one million events using Pythia 8, it was observed that the ratio of negative to positive charged particles in different collision systems match with the data as a function of PDF sets. Also, the ratio of the positive and negative charged particle yields are found not to be due to an initial state, and the linearity in the ratio of hadrons is also a consequence of the linearity in the ratio of the partons of different types that went into the collision before the hadronization step, i.e. a final state effect.
