Query: Charmonium Transverse Momentum Distribution in High Energy Nuclear
  Collisions   The Charmonium transverse momentum distribution is more sensitive to the
nature of the hot QCD matter created in high energy nuclear collisions, in
comparison with the yield. Taking a detailed transport approach for charmonium
motion together with a hydrodynamic description for the medium evolution, the
cancelation between the two hot nuclear matter effects, the dissociation and
the regeneration, controls the charmonium transverse momentum distribution.
Especially, the second moment of the distribution can be used to differentiate
between the hot mediums produced at SPS, RHIC and LHC energies.
