Pythia 8中的多重交互

Multiple Interactions in Pythia 8

Richard Corke

摘要:

模拟强子事件中的多个部分子相互作用对于理解最小偏差物理以及硬过程的潜在事件至关重要。简要概述了当前的Pythia 8多重相互作用(MI)模型,然后查看可以包含在MI框架中的两个其他效应。与再散射,先前散射的部分子被允许参加另一个随后的散射,而与增强屏蔽,不同的初始状态波动的影响进行建模。

英文摘要:

Modelling multiple partonic interactions in hadronic events is vital for understanding minimum-bias physics, as well as the underlying event of hard processes. A brief overview of the current Pythia 8 multiple interactions (MI) model is given, before looking at two additional effects which can be included in the MI framework. With rescattering, a previously scattered parton is allowed to take part in another subsequent scattering, while with enhanced screening, the effects of varying initial-state fluctuations are modelled.
