在标准模型的B-L中寻找LHC处的单Higgs信号

Search for Mono-Higgs Signals at the LHC in the B-L Supersymmetric Standard Model

W. Abdallah, A. Hammad, S. Khalil, S. Moretti

摘要:

我们研究了$B-L$超对称标准模型中出现的单希格斯签名,这些签名是由最小超对称标准模型中不存在的新通道引起的,即,通过拓扑结构,其中介质是重$Z'$,质量为${\cal O}(2~{\rm TeV})$,或中间体$h'$($B-L$起源的最轻CP偶希格斯态),质量为${\cal O}(0.2~{\rm TeV})$。所考虑的单Higgs探针是最近在大型强子对撞机上发现的类SM Higgs态,以加强其质量重建用于背景缩减目的。考虑到这一点,选择了两个最干净的签名:$γγ$和$ZZ^*\to 4l$($l=e,~μ$)。我们展示了如何使用专用的运动学分析,在部分子,淋浴,强子化和探测器效应的存在下,可以预见的能量和光度选项访问这两个。

英文摘要:

We study mono-Higgs signatures emerging in the $B-L$ supersymmetric standard model induced by new channels not present in the minimal supersymmetric standard model, i.e., via topologies in which the mediator is either a heavy $Z'$, with mass of ${\cal O}(2~{\rm TeV})$, or an intermediate $h'$ (the lightest CP-even Higgs state of $B-L$ origin), with mass of ${\cal O}(0.2~{\rm TeV})$. The mono-Higgs probe considered is the SM-like Higgs state recently discovered at the large hadron collider, so as to enforce its mass reconstruction for background reduction purposes. With this in mind, its two cleanest signatures are selected: $γγ$ and $ZZ^*\to 4l$ ($l=e,~μ$). We show how both of these can be accessed with foreseen energy and luminosity options using a dedicated kinematic analysis performed in presence of partonic, showering, hadronisation and detector effects.
