Quarkonium has been regarded as one of the golden probes to identify the phase transition from confined hadronic matter to the deconfined quark-gluon plasma (QGP) in heavy-ion collisions. Recent theoretical developments in the study of the J/ψ and ϒ families at the energies of Large Hadron Collider (LHC) are reviewed. In particular, the possible implications related to the production and propagation of quarkonia in proton-nucleus collisions are discussed. A special emphasis is put on the excited states such as the ψ′, Υ(2S) and Υ(3S).
