Quark-Gluon Plasma Characterisation with Heavy Flavour Probes
Heavy flavor (HF) quarks are excellent probes for the properties of the QGP created in ultra-relativistic heavy-ion collisions. Open HF hadron production allows one to determine the transport coefficients of the QGP. At high transverse momentum, they serve to study parton energy-loss mechanisms in the QGP. Present models, however, differ in many details. In the quarkonia sector, open questions include: up to which temperature can the different quarkonium states survive in a QGP and how do these objects interact with the QGP? How can the recombination of HF quarks/antiquarks from independent hard parton-parton interactions be described in an expanding medium? How constraining is the knowledge of the total HF production crosssection? How do quarkonia interact with the expanding gas of hadrons? Experimentalists and theorists will gather to contribute to answering these questions.
