在LHC测量基础事件和最小偏差

Measurement of the Underlying Event and Minimum Bias at LHC

F. Ambroglini

摘要:

本文讨论了大型强子对撞机(LHC)在标称条件下,用CMS和ATLAS探测器对潜在事件(UE)和最小偏差(MB)的研究。使用带电粒子和带电粒子喷流,将有可能区分不同的QCD模型与不同的多个部分子相互作用方案,正确地再现Tevatron数据,但当外推到LHC能量时给出不同的预测。这将允许在LHC启动时改进和调整Monte Carlo模型,并为探索14 TeV质子-质子碰撞中的QCD动力学开辟了前景。

英文摘要:

A study of Underlying Events (UE) and Minimum Bias (MB) at Large Hadron Collider (LHC)with CMS and ATLAS detector under nominal conditions is discussed. Using charged particle and charged particle jets, it will be possible to discriminate between various QCD models with different multiple parton interaction schemes, which correctly reproduce Tevatron data but give different predictions when extrapolated to the LHC energy. This will permit improving and tuning Monte Carlo models at LHC start-up, and opens prospects for exploring QCD dynamics in proton-proton collisions at 14TeV.
