Measurement of the Z boson plus two b-jets cross section in CMS with 100 pb-1

摘要:

在大型强子对撞机上,可以用大约100 pb-1的数据测量产生Z玻色子和两个相关的b喷注以及Z衰变为轻子的截面。我们使用模拟数据来研究可能的策略,早期测量这个过程与CMS检测器。这个最终状态的速率和运动学性质需要很好地理解,因为它构成了LHC几个希格斯发现通道的总背景的很大一部分。

英文摘要:

The cross section for production of Z bosons with two associated b-jets, and Z decaying to leptons, can be measured at the LHC with about 100 pb-1 of data. We use simulated data to study possible strategies for an early measurement of this process with the CMS detector. The rate and kinematic properties of this final state needs to be well understood because it constitutes a large fraction of the total backgrounds to several of the Higgs discovery channels at the LHC.
