LHC启动时,CMS中的W和Z玻色子生产

W and Z boson Productions in CMS at LHC startup

Didar Dobur

摘要:

我们报告的潜在测量W和Z玻色子生产,以及生产与喷气机。特别感兴趣的是射流多重性和$P_{\rm T}$分布。在大型强子对撞机运行的启动年,预计10到$100 {\rm pb}^{-1}$的数据集可能已经提供了Tevatron对撞机在射流多重性和$P_{\rm T}$范围之外的信息。我们特别感兴趣的是通过将它们与下一个领先阶蒙特卡罗生成器进行比较来理解W+射流与Z+射流分布的比率,因为这些过程为搜索新的物理现象提供了强大的背景。

英文摘要:

We report on potential for measurement of W and Z boson production, as well as the production in association with jets. Of particular interest are jet multiplicity and $P_{\rm T}$ distributions. The 10 to $100 {\rm pb}^{-1}$ datasets expected in the startup year of operation of LHC are likely to already provide information beyond the reach of the Tevatron collider both in jet multiplicity and $P_{\rm T}$ range. We are especially interested in understanding the ratios of W+jets to Z+jets distributions by comparing them to next-to-leading order Monte Carlo generators, as these processes present a formidable background for searches of new physics phenomena.
