We investigate charmonium production in relativistic heavy-ion collisions via a rate equation which comprehensively describes dissociation and regeneration (via $c$ and $\bar c$ quarks) through QGP anined from primordial production including pre-equinsport equation (for primordial production) and a blast-wave approach (for regeneration) are employed to study the transverse momentum distribution of charmonia. The influence of various mechanisms on spectra and rapidity distribution at different collision energies are investigated, and tested with applications to experimental data.
