In this report we review recent progress achieved in the understanding of heavy quarkonium under extreme conditions from a theory perspective. Its focus lies both on quarkonium properties in thermal equilibrium, as well as recent developments towards a genuine real-time description, valid also out-of-equilibrium. We will give an overview of the theory tools developed and deployed over the last decade, including effective field theories, lattice field theory simulations, modern methods for spectral reconstructions and the the open-quantum systems paradigm. The report will discuss in detail the concept of quarkonium melting, providing the reader with a contemporary perspective. In order to judge where future progress is needed we will also discuss recent results from experiments and phenomenological modeling of quarkonium in relativistic heavy-ion collisions.

“…In order to get a quantitative comparison between the two results, we only need to set the value of the strong coupling constant α s in Eqs. (19) and (28). To this end, we evaluate α s -at the energy scale of the mass of the 1S quarkonia states [respectively J/ψ and Υ(1S) in the charmonium and bottomonium 5 For the evaluation of this integral only, we will denote k = k.…”

“…Our results for the spectra and interquark distances are reported in Section IV and our conclusions in Section V. Preliminary versions of our study have been presented in Refs. [26][27][28]. We note again that our aim is to gain a qualitative understanding of the interplay between perturbative and nonperturbative features of the interquark potential.…”

Lattice Gluon Propagator and One-Gluon-Exchange Potential

We consider the interquark potential in the one-gluon-exchange (OGE) approximation, using a fully nonperturbative gluon propagator from large-volume lattice simulations. The resulting V LGP potential is non-confining, showing that the OGE approximation is not sufficient to describe the infrared sector of QCD. Nevertheless, it represents an improvement over the perturbative (Coulomb-like) potential, since it allows the description of a few low-lying bound states of charmonium and bottomonium. In order to achieve a better description of these spectra, we add to V LGP a linearly growing term. The obtained results are comparable to the corresponding ones in the Cornell-potential case. As a byproduct of our study, we estimate the interquark distance for the considered charmonium and bottomonium states.
