用eA对撞机理解饱和和AA碰撞

Understanding saturation and AA collisions with an eA collider

T. Lappi

摘要:

高能核-核碰撞的初始条件由核波函数的小动量分数部分决定。这是胶子饱和的区域,而实验研究它的最直接方法是在高能电子离子对撞机(EIC)上进行深度非弹性散射。这个演讲讨论了EIC物理学和相对论性重离子碰撞初始阶段之间的一些联系。我们认为,在EIC的测量将提供详细的高精度信息的初始条件,横向几何形状和纵向的相关性,这将是至关重要的理解的初始阶段的重离子碰撞的参数。

英文摘要:

The initial conditions in high energy nucleus-nucleus collisions are determined by the small momentum fraction part of the nuclear wavefunction. This is the regime of gluon saturation and the most direct way to experimentally study it would be deep inelastic scattering at a high energy electron ion collider (EIC). This talk discusses some of the connections between physics at the EIC and the initial stage of relativistic heavy ion collisions. We argue that measurements at an EIC will provide detailed high-precision information about the parameters for the initial conditions, transverse geometry and longitudinal correlations that will be crucial in understanding the initial stage of a heavy ion collision.
