【正文】 BenWei Zhang, ICHEP’04, Beijing Heavy Quark VS. Light Quark Energy loss of heavy quark is significantly suppressed due to mass effect, in particular, the deadcone effect. 20 BenWei Zhang, ICHEP’04, Beijing Conclusion ? Heavy quark energy loss induced by gluon radiation is derived in terms of Modified FF with pQCD. ? Two mass effects: (I) Gluon formation time of the heavy quark is reduced relative to that of a light quark: Medium size dependence of heavy quark enegy loss is found to change from a linear to a quadratic form when the initial energy and momentum scale are increasing. (II) Deadcone effect: Heavy quark energy loss is significantly suppressed relative to a light quark. 21 BenWei Zhang, ICHEP’04, Beijing Thank you very much! 謝謝 ! 22 BenWei Zhang, ICHEP’04, Beijing Twist4 Parton Correlation 23 BenWei Zhang, ICHEP’04, Beijing Factorization of Twist4 Matries
