多重散射、潜在事件和最小偏差

Multiple Scattering, Underlying Event, and Minimum Bias

Gosta Gustafson

摘要:

在这次演讲中,我首先讨论了多次散射的实验证据和潜在事件的性质。Rick Field对CDF数据的广泛分析与关于多次碰撞和AGK切割规则的传统观点不一致。数据似乎暗示着某种颜色重组或来自坡密子顶点的意想不到的强烈影响。然后,我讨论的理论思想之间的关系,多次碰撞和幺正性:AGK规则,IP环,偶极级联模型和衍射。

英文摘要:

In this talk I first discuss the experimental evidence for multiple scattering and the properties of the underlying event. The extensive analyses by Rick Field of data from CDF cannot be reconciled with traditional wisdom concerning multiple collisions and the AGK cutting rules. Data seem to imply some kind of color recombination or unexpectedly strong effects from pomeron vertices. I then discuss theoretical ideas concerning the relation between multiple collisions and unitarity: the AGK rules, IP loops, dipole cascade models and diffraction.
