重夸克在退禁闭物质中的辐射和碰撞能量损失

Radiative and Collisional Energy Loss of Heavy Quarks in Deconfined Matter

J. Aichelin, P. B. Gossiaux, T. Gousset

摘要:

本文扩展了我们最近提出的关于夸克-胶子等离子体(QGP)中重夸克碰撞能量损失的模型,引入了辐射能量损失。我们讨论的方法和目前的计算在$\sqrt{s}=2.76 TeV$的PbPb碰撞。本文用Kolb和Heinz等离子体流体力学膨胀模型计算了重夸克的横动量谱、RAA和椭圆流$v_2$。

英文摘要:

We extend our recently advanced model on collisional energy loss of heavy quarks in a quark gluon plasma (QGP) by including radiative energy loss. We discuss the approach and present calculations for PbPb collisions at $\sqrt{s}=2.76 TeV$. The transverse momentum spectra, RAA, and the elliptic flow $v_2$ of heavy quarks have been obtained using the model of Kolb and Heinz for the hydrodynamical expansion of the plasma.
