Heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) results a hot system at energy density. This would result a fluid matter where collective flow is observed at zero viscosity. The suppression of jets are observes in the form of mach cones. This suppression indicates strongly coupled plasma where thermal fluctuations in the plasma characterize the high energy density of the medium. This results in color confinement phase of the quark gluon plasma. The suppression of both light (u, d, s) and heavy (c, b) hadrons is observed at large transverse momenta.
