The diffusion of heavy quarks through the quark–gluon plasma (QGP) as produced in high-
energy heavy-ion collisions has long been recognized as an excellent probe of its transport …

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 …

In the last few years, numerical simulations of Quantum chromodynamics on the lattice have
reached a new level of accuracy. A wide range of thermodynamic quantities is now available …

The production of ground-state and excited bottomonia in ultrarelativistic heavy-ion
collisions is investigated within a kinetic-rate equation approach including regeneration. We …

A bstract We develop a framework of coupled transport equations for open heavy flavor and
quarkonium states, in order to describe their transport inside the quark-gluon plasma. Our …

We perform a comprehensive study of the time evolution of heavy-quarkonium states in an
expanding hot QCD medium by implementing effective field theory techniques in the …

A bstract We solve the Lindblad equation describing the Brownian motion of a Coulombic
heavy quark-antiquark pair in a strongly coupled quark-gluon plasma using the highly …

The future opportunities for high-density QCD studies with ion and proton beams at the LHC
are presented. Four major scientific goals are identified: the characterisation of the …

Prospects for quarkonium-production studies accessible during the upcoming high-
luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed …

Dissociation of quarkonium in quark–gluon plasma (QGP) is a long standing topic in
relativistic heavy-ion collisions because it has been believed to signal one of the …
