在Tevatron上测量潜在事件

Measurement of the Underlying Event at Tevatron

Deepak Kar

摘要:

CDF运行II数据的基础事件与Drell-Yan轻子对生产作为轻子对横动量的函数进行检查。的数据进行了比较与以前的分析的基础事件在高横向动量喷流生产的行为,也与其他几个QCD Monte-Carlo模型。目标是提供可用于调整和改进潜在事件的QCD Monte-Carlo模型的数据,这对于LHC的启动尤为重要。

英文摘要:

CDF Run II data for the underlying event associated with Drell-Yan lepton pair production are examined as a function of the lepton-pair transverse momentum. The data are compared with a previous analysis on the behavior of the underlying event in high transverse momentum jet production and also with several other QCD Monte-Carlo models. The goal is to provide data that can be used to tune and improve the QCD Monte-Carlo models of the underlying event, which is especially important now in view of the LHC startup.
