论文摘要
使用139 fb $^{ - 1} $的Proton-Proton碰撞数据记录在$ \ sqrt {s} $ = 13 TEV的Atlas实验中，使用139 fb $^{ - 1} $在四元衰减通道（其中Lepton = $ e $，$μ$）中研究了Higgs Boson属性。 $ h \ \ zz^*$衰减的包含横截面时间分支比率为$ 1.34 \ pm 0.12 $ pb的希格斯玻色子，绝对速度低于2.5，与标准模型预测非常吻合1.33 \ pm pm 0.08 $ pb。在几个专有的相空间区域中，用于HIGGS玻色子生产模式的横截面时间分支比率是测量的。使用有效的现场理论方法来解释测量值和希格斯玻色子相互作用的张量结构。排除限制设置在Higgs玻色子与矢量玻色子，胶子和顶部夸克的CP-E-E-E-EDD和CP-ODD“超越标准模型”耦合上。
Higgs boson properties are studied in the four-lepton decay channel (where lepton = $e$, $μ$) using 139 fb$^{-1}$ of proton-proton collision data recorded at $\sqrt{s}$ = 13 TeV by the ATLAS experiment at the Large Hadron Collider. The inclusive cross-section times branching ratio for $H\to ZZ^*$ decay is measured to be $1.34 \pm 0.12$ pb for a Higgs boson with absolute rapidity below 2.5, in good agreement with the Standard Model prediction of $1.33 \pm 0.08$ pb. Cross-sections times branching ratio are measured for the main Higgs boson production modes in several exclusive phase-space regions. The measurements are interpreted in terms of coupling modifiers and of the tensor structure of Higgs boson interactions using an effective field theory approach. Exclusion limits are set on the CP-even and CP-odd `beyond the Standard Model' couplings of the Higgs boson to vector bosons, gluons and top quarks.
