Abstract : The Strongly interacting heavy ions turns into a plasma of deconfined quarks and gluons at high temperatures. These deconfined partons represent a new state of matter called QGP, a state well described by statistical QCD. Many experiments have been done to produce such a state in LHC and RHIC. A very important signal for the existence of QGP is the dissociation of quarkonium states. One can investigate the properties of this deconfined medium by performing study on heavy quarks bound states in the medium. A significant related phenomenon is the so-called charmonium suppression, where the color charges of the surrounding light partons (quarks and gluons) screen the charm/beauty quark and its antiquark, preventing the formation of their bound states. We will estimate the suppression of charmonia states caused by color screening in an extending QGP of finite lifetime with the conditions relevant for Pb + Pb collisions. We will use in our studying the properties of charmonia states and recent results on their dissociation temperatures. We will prove that; low bound states e.g. the excited ψ(2S) states, dissociate at higher rate that the highly bound ones e.g. the J/𝜓 ground states, by calculating their survival probability.
