Charm quark diffusion coefficients in the quark-gluon plasma — •Johannes Misch, Moritz Greif, Hendrik van Hees, and Carsten Greiner — Institut fuer Theoretische Physik/ITP, Johann Wolfgang Goethe-Universitaet, Frankfurt am Main

The diffusion of heavy quarks, e.g., charm quarks in a thermal medium can be described by the Fokker-Planck equation. Heavy quarks are important probes of the quark-gluon plasma, and the understanding of their diffusion properties is necessary to explain experimental data. We use the BAMPS (Boltzmann Approach to Multi-Parton Scatterings) simulation framework to determine the drag and diffusion constants. BAMPS uses pQCD matrix elements for binary and inelastic scattering. We study the dependence of the charm quark diffusion on multiple scales of the system, such as charm mass, temperature and ingoing charm momentum.
