【正文】 have been devoted to the calculations of the energy loss of a light quark. ? For massive quarks, the formalism of mediuminduced gluon radiation is not developed to the same extent. Experiment: ? Open charm suppression, which can now be measured at RHIC by paring pt distributions of Dmesons in DAu and AuAu collisions, is a novel probe of QGP dynamics. 5 BenWei Zhang, ICHEP’04, Beijing Heavy Quark Energy Loss ?
