摘要:

我们提出了潜在的发现的标准模型希格斯玻色子产生的矢量玻色子融合机制。我们考虑了希格斯玻色子玻色子衰变到W+W-末态,两个W-玻色子随后都以轻子方式衰变。主要背景是产生一个或多个喷流的ttbar。这项研究是基于一个完整的模拟CMS检测器,和最新的重建代码。结果表明,对于质量在130-200 GeV之间的希格斯玻色子,积分亮度为12-72 1/fb时,可以得到5 σ显著的信号。此外,主背景可以直接从数据测量到7%,积分亮度为30 1/fb。在这项研究中,我们还提出了一种方法来获得信息的希格斯质量的横向质量分布。

英文摘要:

We present the potential for discovering the Standard Model Higgs boson produced by the vector-boson fusion mechanism. We considered the decay of Higgs bosons into the W+W- final state, with both W-bosons subsequently decaying leptonically. The main background is ttbar with one or more jets produced. This study is based on a full simulation of the CMS detector, and up-to-date reconstruction codes. The result is that a signal of 5 sigma significance can be obtained with an integrated luminosity of 12-72 1/fb for Higgs boson masses between 130-200 GeV. In addition, the major background can be measured directly to 7% from the data with an integrated luminosity of 30 1/fb. In this study, we also suggested a method to obtain information in Higgs mass using the transverse mass distributions.
