摘要:

各向异性流是研究重离子碰撞中产生夸克-胶子等离子体(QGP)的初始条件和输运性质的灵敏探针。在这些论文中,我们首次用ALICE探测器测量了$\sqrt{s_{_{\rm NN}}}=$ 5.02 TeV的Pb-Pb碰撞中带电粒子的椭圆流($v_2$)、三角流($v_3$)和四边流($v_4$).此外,将讨论各种理论计算的实验测量的比较。这提供了一个独特的机会来测试的流体动力学图片的有效性,并区分各种可能性之间的温度依赖性的剪切粘度的熵密度比产生的QGP。

英文摘要:

Anisotropic flow is a sensitive probe of the initial conditions and the transport properties of the Quark Gluon Plasma (QGP) produced in heavy-ion collisions. In these proceedings, we present the first results of elliptic ($v_2$), triangular ($v_3$) and quadrangular flow ($v_4$) of charged particles in Pb--Pb collisions at $\sqrt{s_{_{\rm NN}}}=$ 5.02 TeV with the ALICE detector. In addition, the comparison of experimental measurements to various theoretical calculations will be discussed. This provides a unique opportunity to test the validity of the hydrodynamic picture and discriminates between various possibilities for the temperature dependence of shear viscosity to entropy density ratio of the produced QGP.
