用部分子输运模型研究了根s（NN）=200 GeV中心Au+Au碰撞中的两粒子和三粒子方位角关联.用部分子输运模型再现了RHIC实验中在二（三）粒子关联中观察到的背侧的一个驼峰结构，即所谓的“类马赫结构”。结果表明，强的部分子级联可以将部分子耦合在一起，表现出明显的集体行为，即由于大的部分子相互作用截面而产生的部分子类马赫激波。
Two- and three-particle azimuthal correlations have been investigated in central Au+Au collisions at root s(NN)=200 GeV with a partonic transport model. A hump structure on the away side, so-called 'Mach-like structure', which was observed in two- ( three-) particle correlations in RHIC experiments, has been reproduced by the partonic transport model. It indicates that a strong parton cascade can couple partons together to show an apparent collective behaviour, i.e. a partonic Mach-like shock wave, due to a big partonic interaction cross section.
