论文摘要
搜索较重的中性希格斯玻色子，$ a $，腐烂成$ z $ boson和另一个重型希格斯玻色子$ h $，是使用与proton-proton碰撞的139 fb $^{ - 1}相对应的数据样本进行的。该搜索将$ z $玻色子腐烂到电子或imuns中，将$ h $玻色子腐烂成一对$ b $ Quarks或$ w $ bosons。考虑到$ a $ boson的质量范围为230-800 GEV，对于$ h $ boson来说，$ a $ boson和130-700 GEV。数据与标准模型预测的背景非常吻合，因此，设置了$σ\ times b（a \ rightarrow zh）\ times b（h \ rightarrow bb $或$ h \ rightarrow ww）$的95％置信度上限。 $ H \ rightArrow bb $通道的上限在0.0062-0.380 pb范围内，对于$ h \ rightarrow ww $ channel的范围为0.023-8.9 pb。还给出了在两个higgs-doublet模型的上下文中对结果的解释。
A search for a heavy neutral Higgs boson, $A$, decaying into a $Z$ boson and another heavy Higgs boson, $H$, is performed using a data sample corresponding to an integrated luminosity of 139 fb$^{-1}$ from proton-proton collisions at $\sqrt{s}$ = 13 TeV recorded by the ATLAS detector at the LHC. The search considers the $Z$ boson decaying into electrons or muons and the $H$ boson into a pair of $b$-quarks or $W$ bosons. The mass range considered is 230-800 GeV for the $A$ boson and 130-700 GeV for the $H$ boson. The data are in good agreement with the background predicted by the Standard Model, and therefore 95% confidence-level upper limits for $σ\times B(A\rightarrow ZH) \times B(H\rightarrow bb$ or $H\rightarrow WW)$ are set. The upper limits are in the range 0.0062-0.380 pb for the $H\rightarrow bb$ channel and in the range 0.023-8.9 pb for the $H\rightarrow WW$ channel. An interpretation of the results in the context of two-Higgs-Doublet models is also given.
