在13TeV、139fb−1的积分光度下，用ATLAS实验记录的数据研究了标准模型(SM)希格斯玻色子和附加希格斯玻色子的罕见衰变。对于SM-Higgs玻色子双介子衰变的研究，观测(预期)意义为2.0σ(1.7σ)，信号强度为1.2±0.6。对于SM希格斯玻色子的Zγ衰变，观测(预期)意义为2.2σ(1.2σ)，信号强度为2.0−0.9+1.0。对于衰变成光子对的新的重共振态的搜索，搜索的质量范围已经达到3TeV，并且没有观察到明显偏离SM的情况。这些研究让我们对希格斯部门有了更深入的了解。
The rare decays of the Standard Model (SM) Higgs boson and additional Higgs boson are searched for with the data recorded by the ATLAS experiment during the LHC pp collision run at 13 TeV corresponding to an integrated luminosity of 139fb−1 . For the search for the dimuon decay of the SM Higgs boson, the observed (expected) significance is 2.0σ (1.7σ), and the signal strength is 1.2 ± 0.6. For the search for the Zγ decay of SM Higgs boson, the observed (expected) significance is 2.2σ (1.2σ), and the signal strength is 2.0−0.9+1.0 . For the search for new heavy resonance decaying into photon pairs, the mass range of the search has reached 3 TeV and no significant deviation from the SM is observed. These searches provide us a deeper understanding of the Higgs sector.
