相对论重离子碰撞后部分子系统的椭圆流和喷注猝灭

Elliptic Flow and Jet Quenching of a Parton System after Relativistic Heavy Ion Collision

Ghi R. Shin

摘要:

采用结合不确定原理的CGC碎裂方法,求解包含胶子辐射过程的半经典Boltzmann方程,得到了相对论性重离子碰撞后的初始相空间分布.本文给出了相对论重离子碰撞后形成的介质中横动量大于6 $GeV/c$的高$p_T$部分子的衰减率随时间的函数关系。我们计算了椭圆流作为一个碰撞参量,时间和横向动量的函数,并提出了极性各向异性,这给出了颜色的初始条件。

英文摘要:

We obtain the initial phase space distribution after relativistic heavy ion collision by the CGC shattering method incorporating the uncertainty principle and solve the semi-classical Boltzmann equation which includes the gluon radiation processes. We present as a function of time the attenuation rate of high $p_T$ partons, which have transverse momenta over 6 $GeV/c$, in the medium which is formed after relativistic heavy ion collision. We calculate the elliptic flow as a function of an impact parameter, time and transverse momentum and also present the polar anisotropy, which gives the initial condition for color filamentation.
