ATLAS Collaboration

AI总结:

利用 ATLAS 的 13 TeV Run 2 数据,在 $H\to WW^*\to eνμν$ 道测量 VBF 希格斯产生的积分与微分基准截面,并用于约束 EFT 六维算符。

摘要:

在 $H \rightarrow WW^{\ast} \rightarrow eνμν$ 衰变道中,测量希格斯玻色子的矢量玻色子产生截面:既作为对希格斯玻色子产生和衰变性质敏感的运动学可观测量的函数,也在一个基准相空间内进行积分测量。该分析使用 ATLAS 探测器在 LHC 第 2 次运行期间、质心系能量 $\sqrt{s}=13$ TeV、对应 139 fb$^{-1}$ 积分亮度所收集的质子-质子碰撞数据。通过选择来自一对 $W$ 玻色子并与希格斯玻色子衰变相容的一个电子和一个 μ 子,研究不同味末态。数据经过探测器非效率和分辨率效应的校正,并将测量结果与不同的最新理论预测进行比较。微分截面被用于约束有效场论中由六维算符描述的反常相互作用。

英文摘要:

The vector-boson production cross-section for the Higgs boson decay in the $H \rightarrow WW^{\ast} \rightarrow eνμν$ channel is measured as a function of kinematic observables sensitive to the Higgs boson production and decay properties as well as integrated in a fiducial phase space. The analysis is performed using the proton-proton collision data collected by the ATLAS detector in Run 2 of the LHC at $\sqrt{s}= 13$ $\text{TeV}$ center-of-mass energy corresponding to an integrated luminosity of 139 fb$^{-1}$. The different flavor final state is studied by selecting an electron and a muon originating from a pair of $W$ bosons and compatible with the Higgs boson decay. The data are corrected for the effects of detector inefficiency and resolution, and the measurements are compared with different state-of-the-art theoretical predictions. The differential cross-sections are used to constrain anomalous interactions described by dimension-six operators in an Effective Field Theory.
