Charmonium dissociation and recombination at LHC: Revisiting comovers

We present our results on charmonium production at the Large Hadron Collider energies within the comover interaction model. The formalism includes both comover dissociation of J/ψJ/ψ's and possible secondary J/ψJ/ψ production through recombination. The estimation of this effect is made without involving free parameters. The comover interaction model also incorporates an analytic treatment of initial-state nuclear shadowing. With these tools, the model successfully describes the centrality, transverse momentum and rapidity dependence of the experimental data from PbPb collisions at the LHC energy of s=2.76 TeV. We present predictions for PbPb collisions at s=5.5 TeV.
