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/psi's and possible secondary J/psi 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 root s. = 2.76 TeV. We present predictions for PbPb collisions at root s. = 5.5 TeV. (C) 2014 The Author. Published by Elsevier B.V.
