用早期数据测量ATLAS上的Z玻色子横动量谱

Measurement of the Z boson transverse momentum spectrum on ATLAS with early data

Lashkar Kashif

摘要:

欧洲核子研究中心大型强子对撞机的第一批数据的基准分析之一将是Z玻色子横向动量谱的测量。在这篇文章中,我提出了一个前瞻性的分析,这种测量在双μ子通道的ATLAS实验。该分析使用模拟数据集的质心能量为10 TeV。在总结了测量的动机之后,我讨论了Z玻色子的选择标准,可能的物理背景和背景去除技术,重点是数据驱动的背景确定。最后,我对2009-10年预计的碰撞数据进行了展望。

英文摘要:

One of the benchmark analyses to be performed with the first data at the CERN Large Hadron Collider will be the measurement of the Z boson transverse momentum spectrum. In this article, I present a prospective analysis for this measurement in the dimuon channel on the ATLAS experiment. The analysis uses simulated datasets at a center-of-mass energy of 10 TeV. After summarizing the motivations for the measurement, I discuss the Z boson selection criteria, possible physics backgrounds, and background removal techniques with a focus on data-driven background determination. I conclude with an outlook toward the collision data expected in 2009-10.
