Motivation ? Modified heavy quark fragmentation function ? Heavy quark energy loss Heavy VS. Light ? Conclusion 3 BenWei Zhang, ICHEP’04, Beijing Jet Quenching Jet quenching has been discovered at RHIC as a good probe of the hot/dense matter. hadrons ph parton E . Wang, nuclth/0405017 4 BenWei Zhang, ICHEP’04, Beijing From Light to Heavy Theory: ? A lot of theoretical studies have been devoted to the calculations
