重离子碰撞的初始条件与高能因子分解

Initial conditions of heavy ion collisions and high energy factorization

T. Lappi

摘要:

色玻璃凝聚是对高能强子或原子核中小动量分数x自由度的有效理论描述,它可以用强经典胶子场来理解。我们讨论了相对论性重离子碰撞中初始条件的结果图像。我们描述了最近的工作表明,领先的碰撞能量可以分解成小x波函数的重整化群演化。然后,我们描述了这个框架可以用来理解的RHIC实验观察到的长程快度相关。

英文摘要:

The Color Glass Condensate is an effective theory description for the small momentum fraction x degrees of freedom in a high energy hadron or nucleus, which can be understood in terms of strong classical gluon fields. We discuss the resulting picture of the initial conditions in a relativistic heavy ion collision. We describe recent work to show that the leading logarithms of the collision energy can be factorized into the renormalization group evolution of the small x wavefunction. We then describe how this framework can be used to understand the long range rapidity correlations observed by the RHIC experiments.
