论文摘要
出现了搜索狭窄的宽大共振衰减到一对Higgs玻色子中的产生，并介绍了将其腐烂到BBZZ通道。该分析基于2016年与CMS检测器收集的数据，在LHC处的Proton-Proton碰撞中，对应于35.9 fb $^{ - 1} $的集成光度。最终所考虑的状态是其中一个Z玻色子腐烂成一对im或电子的状态，而另一个Z玻色子腐烂到一对夸克或一对中微子。在有和没有扩展的Higgs扇区的模型中，在95％置信水平的上限置于95％的置信水平上，这些狭窄的旋转-0或Spin-2颗粒腐烂到一对Higgs玻色子。对于共振质量在260至1000 GEV之间，生产横截面上的限制了SPIN-0和SPIN-2共振的分支分数分别为0.1至5.0 pb和0.1至3.6 pb。这些结果设置了散装randall-sundrum radion，重力的kaluza-klein激发和N2HDM模型中的参数空间的限制。对于参数的特定选择，可以将N2HDM排除在360至620 GEV之间的质量范围内，以使共鸣衰减到两个Higgs玻色子。这是在BBZZ频道中首次搜索Higgs Boson共振对生产。
A search for the production of a narrow-width resonance decaying into a pair of Higgs bosons decaying into the bbZZ channel is presented. The analysis is based on data collected with the CMS detector during 2016, in proton-proton collisions at the LHC, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The final states considered are the ones where one of the Z bosons decays into a pair of muons or electrons, and the other Z boson decays either to a pair of quarks or a pair of neutrinos. Upper limits at 95% confidence level are placed on the production of narrow-width spin-0 or spin-2 particles decaying to a pair of Higgs bosons, in models with and without an extended Higgs sector. For a resonance mass range between 260 and 1000 GeV, limits on the production cross section times branching fraction of a spin-0 and spin-2 resonance range from 0.1 to 5.0 pb and 0.1 to 3.6 pb, respectively. These results set limits in parameter space in bulk Randall-Sundrum radion, Kaluza-Klein excitation of the graviton, and N2HDM models. For specific choices of parameters the N2HDM can be excluded in a mass range between 360 and 620 GeV for a resonance decaying to two Higgs bosons. This is the first search for Higgs boson resonant pair production in the bbZZ channel.
