论文摘要
在2018年，CMS报告了Light Higgs-Boson搜索的多余，以大约95GEV为基于运行1和第一年运行2个数据的Diphoton衰减模式。多余的局部意义合并为$ 2.8 \，σ$。多余的与从二光子搜索通道中的地图集搜索中获得的限制兼容。最近，CMS报告了另一个局部过量，其在二托最终状态的轻higgs-boson搜索中的显着性为$ 3.1 \，σ$，这与对Higgs玻色子的解释兼容，质量约为95GEV。我们表明，观察到的结果可以解释为具有额外的真实单曲（N2HDM）的两吉格双重双线模型中希格斯玻色子的表现。我们发现，N2HDM的最轻的希格斯玻色子可以同时适合两者，而第二高的状态使其满足125GEV处的Higgs-Boson测量值，并且完整的Higgs-Boson部门与HIGG的所有HIGG均与LEP的搜索相兼容，并且与Tevatron的搜索相兼容，并且是lhc的lhc and lhc，约束。最后，我们证明，可以在两个搜索渠道中观察到的CMS与本地$ 2.3 \，σ$多余的$ b \ bar b $最终状态在同一质量范围内观察到的最终状态。
In 2018 CMS reported an excess in the light Higgs-boson search in the diphoton decay mode at about 95GeV based on Run 1 and first year Run 2 data. The combined local significance of the excess was $2.8\,σ$. The excess is compatible with the limits obtained in the ATLAS searches from the diphoton search channel. Recently, CMS reported another local excess with a significance of $3.1\,σ$ in the light Higgs-boson search in the di-tau final state, which is compatible with the interpretation of a Higgs boson with a mass of about 95GeV. We show that the observed results can be interpreted as manifestations of a Higgs boson in the Two-Higgs Doublet Model with an additional real singlet (N2HDM). We find that the lightest Higgs boson of the N2HDM can fit both excesses simultaneously, while the second-lightest state is such that it satisfies the Higgs-boson measurements at 125GeV, and the full Higgs-boson sector is compatible with all Higgs exclusion bounds from the searches at LEP, the Tevatron and the LHC as well as with other theoretical and experimental constraints. Finally, we demonstrate that it is furthermore possible to accommodate the excesses observed by CMS in the two search channels together with a local $2.3\,σ$ excess in the $b \bar b$ final state observed at LEP in the same mass range.
