在LHC运行2上对重中性希格斯玻色子的模型无关探测的进一步研究

Further Investigation on Model-Independent Probe of Heavy Neutral Higgs Bosons at the LHC Run 2

Yu-Ping Kuang, Hong-Yu Ren, Ling-Hao Xia

摘要:

在我们的前一篇论文中,我们基于dim-6相互作用的有效拉格朗日公式,给出了最轻的希格斯玻色子$h$(类SM)和较重的中性希格斯玻色子$H$的一般有效Higgs相互作用,并提出了探测$H$的两个灵敏过程.我们在几个例子中表明,$H$的共振峰和它的dim-6有效耦合常数(ECC)可以在LHC运行2检测到合理的积分亮度。在本文中,我们进一步进行了更深入的研究,最敏感的过程,$pp\to VH^\ast\to VVV$,之间的关系的信息$1σ,\,3σ,\,5σ$统计意义和相应的范围的Higgs ECC的积分亮度为100 fb $^{-1}$。这些结果在LHC运行2中有两个有用的应用:(A)如果发现了$H$,则实现了dim-6相互作用ECC的实验测定;(B)如果没有发现$H$,则获得了理论上的不相容边界。

英文摘要:

In our previous paper, we provided general effective Higgs interactions for the lightest Higgs boson $h$ (SM-like) and a heavier neutral Higgs boson $H$ based on the effective Lagrangian formulation up to the dim-6 interactions, and then proposed two sensitive processes for probing $H$. We showed in several examples that the resonance peak of $H$ and its dim-6 effective coupling constants (ECC) can be detected at the LHC Run 2 with reasonable integrated luminosity. In this paper, we further perform a more thorough study of the most sensitive process, $pp\to VH^\ast\to VVV$, on the information about the relations between the $1σ,\,3σ,\,5σ$ statistical significance and the corresponding ranges of the Higgs ECC for an integrated luminosity of 100 fb$^{-1}$. These results have two useful applications in the LHC Run 2: (A) realizing the experimental determination of the ECC in the dim-6 interactions if $H$ is found and, (B) obtaining the theoretical exclusion bounds if $H$ is not found. Some alternative processes sensitive for certain ranges of the ECC are also analyzed.
