le Scattering in Nuclei In order to calculate the heavy quark energy loss induced by gluon radiation in pQCD, we should separate the ‘hard’ part from the ‘soft’ part: factorizing. 9 BenWei Zhang, ICHEP’04, Beijing Generalized Factorization Luo, Qiu, Sterman, PLB 279(1992)377。 Luo, Qiu, Sterman, PRD 49(1994)4493。 PRD 50(1994)1951 10 BenWei Zhang, ICHEP’04, Beijing Tensor Structure • Making a collinear approximation: • The tensor structure can be factorized as: 11 BenWei Zhang, ICHEP’04, Beijing LPM Effect LMP interference effect. The formation time of gluon radiation. 12 BenWei Zhang, ICHEP’04, Beijing Other Processes 13 BenWei Zhang, ICHEP’04, Beijing DeadCone Effect Deadcone effect of heavy quark propagating will suppress gluon radiation at small angles. 14 BenWei Zhang, ICHEP’04, Beijing Modified F。阅读剩余 0%
