It has been found that the nuclear modification factor of a J/Psi meson shows no significant dependence on centrality when going from Relativistic Heavy Ion Collider (RHIC) energy to Large Hadron Collider (LHC) energy, and it is believed that the regeneration of the J/Psi meson plays an important role in the production of J/Psi mesons. In this work we investigate the effects of the J/Psi meson production by charm quark coalescence on the nuclear modification factor in heavy ion collisions. We find that the charm quark coalescence of J/Psi meson is mainly responsible for the J/psi production in low transverse momentum region.
