Herwig++中的软相互作用

Soft interactions in Herwig++

Manuel Bahr, Jonathan M. Butterworth, Stefan Gieseke, Michael H. Seymour

摘要:

我们描述了最近的事态发展,扩展的多部分子相互作用模型的基础事件Herwig++到软,非微扰,政权。这使得该程序也可以描述最小偏置碰撞,其中没有硬相互作用,第一次。从2.3版开始,它是公开可用的,并描述了Tevatron基础事件和最小偏倚数据。然而,正如我们所讨论的,对大型强子对撞机的外推仍然存在相当大的模糊性。

英文摘要:

We describe the recent developments to extend the multi-parton interaction model of underlying events in Herwig++ into the soft, non-perturbative, regime. This allows the program to describe also minimum bias collisions in which there is no hard interaction, for the first time. It is publicly available from versions 2.3 onwards and describes the Tevatron underlying event and minimum bias data. The extrapolations to the LHC nevertheless suffer considerable ambiguity, as we discuss.
