The classical pattern, already proposed in both Greek and Hindu philosophy has the form of four fundamental states like solid, liquid, gas and plasma, the vacuum is added as fifth element, providing the space in which matter exists. But these states of matter can’t analyze the sub atomic world of strong interactions. The main impetus for the field of relativistic heavy-ion collisions since its inception with nuclear beams at the synchrophasotran, Dubna, AGS and SPS, Cern for more than 20 years ago has been focused to study the properties of nuclear matter under conditions of extremely high density and pressure. As QCD became recognized as the appropriate theory of the strong interaction, it was realized that at nuclear densities of GeV/fm3 or temperatures of T~170 MeV a hadronic picture of matter would break down and matter should more appropriately be described as existing in a deconfined quark gluon plasma state. The reasons for investigating the production mechanism of secondary particles in heavy ion interaction might provide some valuable information about reaction mechanism in the nucleus-nucleus collisions. In relativistic heavy ion collisions, the secondary hadrons are formed instantaneously. There is a formation time between the collision and hadronization of the final state particles. The hadronize within the target nucleus and may re-interact with the surrounding target matter and produce cascade particles. Moreover, characteristics of secondary charged particles produced in such collisions may be obtained by analyzing the experimental data on the secondary charged particles.
