Heavy quark dynamics in the QGP: Towards a solution of the RAA and ν2 puzzle
2016
The two key observables related to heavy quarks that have been measured in experiments are the nuclear suppression factor R AA and the elliptic flow ν 2 . The simultaneous reproduction of these two observables is a puzzle which have challenged all the existing models. We discuss two ingredients responsible for addressing a large part of such a puzzle: the temperature dependence of the energy loss and the full solution of the Boltzmann collision integral for the scattering between the heavy quarks and the particle of the bulk.
