论文摘要
搜索带电的希格斯玻色子h $^\ pm $ $ $ n衰变成沉重的中性希格斯玻色子H，并提出了W Boson。该分析将H衰减靶向一对tau钩子，其中至少有一个衰减强调，并在此事件中带有额外的电子或μ子。该搜索基于CMS实验在2016-2018期间记录的Proton-Proton碰撞数据，$ \ sqrt {s} $ = 13 TEV，对应于138 fb $^{ - 1} $的集成光度。数据与标准模型背景期望一致。假设H $^\ pm $在300-700 GEV的跨截面和分支分数的乘积上设置为95％置信度的上限，假设质量为200 GEV，则将上限设置为300-700 GEV的质量范围。观察到的极限范围从0.085 pb的h $^\ pm $ 300 GEV的质量到0.019 pb，质量为700 GEV。这些是H $^\ pm $生产在H $^\ pm $ $ \至$ hw $^\ pm $ decay频道中的第一个限制。
A search for a charged Higgs boson H$^\pm$ decaying into a heavy neutral Higgs boson H and a W boson is presented. The analysis targets the H decay into a pair of tau leptons with at least one of them decaying hadronically and with an additional electron or muon present in the event. The search is based on proton-proton collision data recorded by the CMS experiment during 2016-2018 at $\sqrt{s}$ = 13 TeV, corresponding to an integrated luminosity of 138 fb$^{-1}$. The data are consistent with standard model background expectations. Upper limits at 95% confidence level are set on the product of the cross section and branching fraction for an H$^\pm$ in the mass range of 300-700 GeV, assuming an H with a mass of 200 GeV. The observed limits range from 0.085 pb for an H$^\pm$ mass of 300 GeV to 0.019 pb for a mass of 700 GeV. These are the first limits on H$^\pm$ production in the H$^\pm$ $\to$ HW$^\pm$ decay channel at the LHC.
