“…The fate of quarkonia -for example the J/ψ and the Υ meson families -in a thermal medium, such as the quark-gluon plasma (QGP) created in heavy ion collisions (HIC), can help us characterize its properties. In particular, quarkonia are sensitive to the space-time temperature profile and transport coefficients of the QGP, see [1][2][3] for recent reviews. Experimentally, a key observable that carries such information is the nuclear modification factor of the yields of quarkonia in nucleusnucleus (AA) collisions, when compared to their yields in nucleon-nucleon (N N ) collisions scaled with the number of binary interactions…”

We present new results for the suppression of high transverse momentum charmonium [J/ψ, ψ(2S)] and bottomonium [Υ(1S), Υ(2S), Υ(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 QQ 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 2.76 TeV 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.

“…The extraction of the spectral function from imaginary time data is chal-lenging as this requires an analytic continuation to real time, but much progress has occurred since the early efforts [48,[51][52][53][54][55][56][57]. We will not review this progress here but refer the readers to excellent reviews on this topic [58][59][60].…”

In relativistic heavy ion collisions at RHIC and the LHC, a quark-gluon plasma (QGP) is created for a short duration of about 10 fm/c. Quarkonia (bound states of cc and bb) are sensitive probes of this phase on length scales comparable to the size of the bound states which are less than 1 fm. Observations of quarkonia in these collisions provide us with a lot of information about how the presence of a QGP affects various quarkonium states. This has motivated the development of the theory of heavy quarks and their bound states in a thermal medium, and its application to the phenomenology of quarkonia in heavy ion collisions. We review some of these developments here.
