pp碰撞和DIS中的多重相互作用、饱和和终态

Multiple Interactions, Saturation, and Final States in pp Collisions and DIS

Gösta Gustafson

摘要:

在高能碰撞中,饱和和多次碰撞最容易在横坐标空间中解释,而动量空间中的分析更适合于计算排他性末态的性质。在这次演讲中,我描述了穆勒的偶极子级联模型的扩展,它试图结合这两种描述的好功能。除了饱和,它还包括相关性和波动的影响,这在以前的方法中很难解释。该模型成功地再现总的,弹性的,衍射截面在pp碰撞和DIS,和最终状态的描述将很快准备就绪。

英文摘要:

In high energy collisions saturation and multiple collisions are most easily accounted for in transverse coordinate space, while analyses in momentum space have been more suitable for calculating properties of exclusive final states. In this talk I describe an extension of Mueller's dipole cascade model, which attempts to combine the good features of both these descriptions. Besides saturation it also includes effects of correlations and fluctuations, which have been difficult to account for in previous approaches. The model reproduces successfully total, elastic, and diffractive cross sections in pp collisions and DIS, and a description of final states will be ready soon.
