Beschreibung
In this talk I concentrate on two very important coefficients in the open-quantum system description of quarkonium in media, namely the mass shift \gamma and the width \kappa. I illustrate recent developments related to the differences in the definitions pertaining to heavy quarkonia and to isolated heavy quark and I discuss their impact on perturbative, lattice and holographic determinations.
