Flow of Heavy Quarks

Derek Teaney
Brookhaven National Laboratory

First I review the typical transport times in the Quark Gluon Plasma (QGP) and hydrodynamic simulations of heavy ion collisions. Then I formulate a Langevin model for the diffusion of heavy quarks within the QGP. Measured Charm quark flow puts a constraint on the typical diffusion coefficient of the charm quark. Finally I discuss how transport processes influence the current-current correlator as measured by the Euclidean Lattice. Precise lattice data could also constrain the heavy quark diffusion coefficient.
