Abstract
⺠We compute charm drag and diffusion in a pion gas (in heavy ion collisions). ⺠We employ effective theory (both chiral and heavy quark). ⺠We unitarize the perturbative amplitude for realistic cross-sections. ⺠A charm quark with momentum 1 GeV loses 50 MeV per fermi (drag). ⺠The momentum distribution broadens some 100 MeV per fermi (diffusion).
