摘要:

在包含韧致辐射$2 \leftrightarrow 3$过程的3+1维部分子输运模型BAMPS中研究了QCD物质的快速热化和强椭圆流的建立.在相同的框架下,可以理解RHIC上Au+Au碰撞中胶子喷流的淬灭。本文在静态箱中研究了胶子喷流在小耗散和大耗散两种情况下锥形结构的发展。此外,我们展示了两种不同的方法来提取的剪切粘度系数$η$从显微照片。

英文摘要:

Fast thermalization and a strong build up of elliptic flow of QCD matter were investigated within the pQCD based 3+1 dimensional parton transport model BAMPS including bremsstrahlung $2 \leftrightarrow 3$ processes. Within the same framework quenching of gluonic jets in Au+Au collisions at RHIC can be understood. The development of conical structure by gluonic jets is investigated in a static box for the regimes of small and large dissipation. Furthermore we demonstrate two different approaches to extract the shear viscosity coefficient $η$ from a microscopical picture.
