We present new results for the suppression of high transverse momentum charmonium [J/psi,psi(2S)] and bottomonium [gamma(1S),gamma(2S),gamma(3S)] states in Pb+Pb collisions at the Large Hadron Collider. Our theoretical formalism combines the collisional dissociation of quarkonia, as they propagate in the quark-gluon plasma, with the thermal wavefunction effects due to the screening of the Q (Q) over bar attractive potential in the medium. We find that a good description of the relative suppression of the ground and higher excited quarkonium states, transverse momentum and centrality distributions is achieved, when comparison to measurements at a center-of-mass energy of 2.76TeV is performed. Theoretical predictions for the highest Pb+ Pb center-of-mass energy of 5.02 TeV at the LHC, where new experimental results are being finalized, are also presented. (C) 2018 The Author(s).
