ATLAS中电弱双玻色子的产生

Electroweak di-boson production in ATLAS

Johannes Ebke

摘要:

在大型强子对撞机时代,对标准模型的弱电部分有一个很好的理解是至关重要的。因此,确定电弱过程的横截面是非常重要的,这既是希格斯玻色子搜索的先决条件,也是测量本身的先决条件。在这次会议上,我们准备了2010年和2011年使用ATLAS探测器获得的\sqrt{s} = 7 TeV质子-质子碰撞数据的几个新测量:使用2010年收集的37 pb^{-1}测量孤立双光子截面,使用2011年收集的205 pb^{-1}测量WZ产生截面。此外,为了对电弱扇区有一个完整的认识,还介绍了已发表的Wγ和Zγ截面以及WW截面的测量结果。

英文摘要:

In the LHC era, it is crucial to gain a good understanding of the electroweak sector of the Standard Model (SM). Determining the cross-sections of electroweak processes is therefore of great importance, both as prerequisites to Higgs-Boson searches as well as measurements in their own right. For this conference, several new measurements with the data from proton-proton collisions at \sqrt{s} = 7 TeV taken in 2010 and 2011 with the ATLAS detector have been prepared: A measurement of the isolated di-photon cross-section using 37 pb^{-1} collected in 2010 and a measurement of the WZ production cross-section using 205 pb^{-1} collected in 2011. In addition and for a complete view of the electroweak sector, the already published measurements of the Wγand Zγcross-sections and the WW cross-sections are presented as well.
