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 …

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 …

The ultrarelativistic heavy-ion programs at the Relativistic Heavy Ion Collider and the Large
Hadron Collider have entered an era of quantitative analysis of quantum chromodynamics …

While perturbative QCD is sufficient for understanding the color, mass and energy
dependences of parton energy loss and jet quenching at large transverse momentum in …

This paper is a write-up of the ideas that were presented, developed and discussed at the
third International Workshop on QCD Challenges from pp to A–A, which took place in August …

Nonperturbative methods play an important role in quantum many-body systems, especially
in situations with an interplay of continuum and bound states and/or large coupling strengths …

In the last decade a Quasi-Particle Model (QPM) has been developed to study charm quark
dynamics in ultra-relativistic heavy-ion collisions supplying a satisfactory description of the …

The propagation of a low momentum heavy quark in a deconfined quark-gluon plasma can
be understood in terms of a Langevin description. The momentum exchange with the …

The in-medium color potential is a fundamental quantity for understanding the properties of
the strongly coupled quark-gluon plasma (sQGP). Open and hidden heavy-flavor (HF) …

We study the hot medium effects in high-multiplicity proton–proton (pp) collisions at\(\sqrt {s_
{NN}}= 13\) TeV via the charmonium probes. The hot medium is described with the …
