The scattering of electroweak bosons tests the gauge structure of the Standard Model and is sensitive to anomalous quartic gauge couplings. In this paper, we present recent results on vector-boson scattering from the ATLAS experiment using proton–proton collisions with a center-of-mass energy of 13 TeV at the LHC. This includes the observation of [Formula: see text], [Formula: see text], and same-sign [Formula: see text] production via vector-boson scattering along with a measurement of [Formula: see text] production ([Formula: see text] denotes [Formula: see text] or [Formula: see text] boson) in semileptonic final states. The results can be used to constrain new physics that manifests as anomalous electroweak-boson self-interactions. Finally, predicted cross-sections for the electroweak scattering of two same-sign [Formula: see text] bosons in association with two jets are compared for a number of generators.

使用 ATLAS 探测器观察和测量矢量玻色子散射

电弱玻色子的散射测试了标准模型的规范结构,并且对异常的四次规范耦合很敏感。在本文中,我们展示了来自 ATLAS 实验的矢量玻色子散射的最新结果,该实验使用 LHC 的质心能量为 13 TeV 的质子-质子碰撞。这包括通过矢量-玻色子散射观察 [公式:参见文本]、[公式:参见文本] 和同号 [公式:参见文本] 产生以及 [公式:参见文本] 产生([公式:see text] 表示半轻末态的 [Formula: see text] 或 [Formula: see text] boson)。结果可用于约束表现为异常电弱玻色子自相互作用的新物理。最后,预测两个相同符号的电弱散射的横截面[公式:
