【正文】 DAu and AuAu collisions, is a novel probe of QGP dynamics. 5 BenWei Zhang, ICHEP’04, Beijing Heavy Quark Energy Loss ? There are several theoretical calculations to obtain the heavy quark energy loss: . Dokshitzer and . Kharzeev M. Djordjevic and M. Gyulassy , E. Wang and . Wang N. Armesto, C. Salgado and U. Wiedemann …… ? Twist Expansion approach in pQCD . Zhang, E. Wang and . Wang, PRL 93(2020) 072301 6 BenWei Zhang, ICHEP’04, Beijing Jet quenching with pQCD ? How to measure the parton energy loss? ? Direct measurement is impossible ? Particle distributions within a jet ? Modification to Fragmentation Function ? Obtain the energy loss indirectly from measuring the modification of FF hadrons ph parton E 7 BenWei Zhang, ICHEP’04, Beijing Heavy Quark ?
