标题： Investigation of jet quenching and elliptic flow within a pQCD-based partonic transport model

摘要： 部分输运模型BAMPS（一种多部分子散射的玻尔兹曼方法）被用于在基于微扰QCD的共同框架下研究重离子碰撞的不同方面。 本报告关注在200 AGeV重离子碰撞中，所产生介质的集体行为和高pT胶子穿过该介质时的能量损失的联合研究。 为此，使用BAMPS模拟了重离子碰撞中胶子的椭圆流和核修改因子。 详细研究了BAMPS中高能胶子的能量损失机制。 为此，将纯弹性相互作用与基于Gunion和Bertsch矩阵元实现的辐射过程gg -> ggg进行了比较。 结果发现，后者是本文所采用框架中能量损失的主要来源。 显示英文摘要

摘要： The partonic transport model BAMPS (a Boltzmann approach to multiparton scatterings) is employed to investigate different aspects of heavy ion collisions within a common framework based on perturbative QCD. This report focuses on the joint investigation of the collective behavior of the created medium and the energy loss of high-pT gluons traversing this medium. To this end the elliptic flow and the nuclear modification factor of gluons in heavy ion collisions at 200 AGeV are simulated with BAMPS. The mechanism for the energy loss of high energy gluons within BAMPS is studied in detail. For this, purely elastic interactions are compared to radiative processes, gg -> ggg, that are implemented based on the matrix element by Gunion and Bertsch. The latter are found to be the dominant source of energy loss within the framework employed in this work.
