论文摘要
本文搜索了搜索新的共鸣，将衰减成$ z $或$ w $玻色子和125 Gev higgs boson $ h $，它的目标是$ν\barνb\ bar {b} $，$ \ ell^+ell^+el^+el^+\ ell^ell^ell^ell^ell^bar^bar {b} b} b} $ pm { $ \ ell = e $或$μ$，proton-proton碰撞，$ \ sqrt {s} = 13 $ tev。所使用的数据对应于Atlas检测器在CERN的LHC运行2期间收集的139 fb $^{ - 1} $的总集成光度。搜索是通过检查$ ZH $或$ WH $候选者的重建不变或横向质量分布的证据，以证明质量超过220 GEV到5 TEV的局部过量。未观察到显着的过量，并将95％的置信度上限在1.3 pb和0.3 fb之间放置在中性和带电的SPIN-1共振和CP-ODD标量玻色子的生产横截面分支部分。这些限制被转换为重矢量三重态模型和两吉格斯二键模型的参数空间的约束。
This article presents a search for new resonances decaying into a $Z$ or $W$ boson and a 125 GeV Higgs boson $h$, and it targets the $ν\barνb\bar{b}$, $\ell^+\ell^-b\bar{b}$, or $\ell^{\pm}νb\bar{b}$ final states, where $\ell=e$ or $μ$, in proton-proton collisions at $\sqrt{s}=13$ TeV. The data used correspond to a total integrated luminosity of 139 fb$^{-1}$ collected by the ATLAS detector during Run 2 of the LHC at CERN. The search is conducted by examining the reconstructed invariant or transverse mass distributions of $Zh$ or $Wh$ candidates for evidence of a localised excess in the mass range from 220 GeV to 5 TeV. No significant excess is observed and 95% confidence-level upper limits between 1.3 pb and 0.3 fb are placed on the production cross section times branching fraction of neutral and charged spin-1 resonances and CP-odd scalar bosons. These limits are converted into constraints on the parameter space of the Heavy Vector Triplet model and the two-Higgs-doublet model.
