在$\sqrt{s}=8$ TeV的PDMATHAAB碰撞中产生$Wγγ$的证据和与ATLAS探测器的反常四次规范耦合的极限

Evidence of $Wγγ$ production in $pp$ collisions at $\sqrt{s}=8$ TeV and limits on anomalous quartic gauge couplings with the ATLAS detector

ATLAS Collaboration

摘要:

这封信报告了三重规范玻色子产生$pp\to W(\ellν)γγ+ X$的证据,这是第一次与8 TeV的LHC数据集。该过程的基准横截面在对应于20.3 fb $^{-1}$的积分光度的数据样本中测量,该数据样本由ATLAS探测器在2012年收集。使用$W$玻色子衰变到$eν$或$μν$以及需要两个孤立光子来选择事件。测量的截面被用来设置限制异常的四次规范耦合在高双光子质量区域。

英文摘要:

This Letter reports evidence of triple gauge boson production $pp\to W(\ellν)γγ+ X$, which is accessible for the first time with the 8 TeV LHC data set. The fiducial cross section for this process is measured in a data sample corresponding to an integrated luminosity of 20.3 fb$^{-1}$, collected by the ATLAS detector in 2012. Events are selected using the $W$ boson decay to $eν$ or $μν$ as well as requiring two isolated photons. The measured cross section is used to set limits on anomalous quartic gauge couplings in the high diphoton mass region.
