使用ATLAS进行最小偏倚和基础事件测量

Minimum Bias and Underlying Event Measurements with ATLAS

Michael Leyton

摘要:

一些最近的最小偏差和基本事件测量的ATLAS合作的摘要。本文给出了在质量中心能量为sqrt(s)= 0.9,2.36和7 TeV的LHC上用低光度质子-质子碰撞数据进行的几种分析的结果。将数据与几个不同的蒙特卡罗事件发生器的预测进行比较。的测量暴露的唯象模型的局限性,在适当地描述在相空间的所有区域中的测量的可观测量。

英文摘要:

A summary of some of the recent minimum bias and underlying event measurements by the ATLAS collaboration is given. The results of several analyses using low-luminosity proton-proton collision data from the LHC taken at center-of-mass energies of sqrt(s) = 0.9, 2.36 and 7 TeV are presented. Data are compared to predictions by several different Monte Carlo event generators. The measurements expose limitations of the phenomenological models in properly describing the measured observables in all regions of phase space.
