摘要:

在这项工作中,我们研究了一个镜像模型与反跷跷板中微子质量,其中对称性破缺的尺度是固定的边界中的中微子部门。该模型的希格斯扇区有两个双重态和中性单态。镜像模型可以在几个方面在LHC能量下进行检验。镜像模型的两个非常独特的特征是一个新的中性规范玻色子$Z^{\prime}$,具有高的不可见分支比,以及通过衰变$Z^{\prime} \rightarrow N +\bar ν$产生的重马约拉纳中微子。这个结果进行了比较,通过重对生产和随之而来的同号双轻子生产重Majorana生产。镜像模型的另一个重要结果是希格斯质量的预测。一个特殊的解导致希格斯粒子出现在与标准模型相同的区域。然而,还有另一个自然的解决方案,希格斯粒子的质量超过400 GeV。

英文摘要:

In this work we study a mirror model with inverse seesaw neutrino masses in which symmetry breaking scales are fixed from bounds in the neutrino sector. The Higgs sector of the model has two doublets and neutral singlets. The mirror model can be tested at the LHC energies in several aspects. Two very distinctive signatures of the mirror model are a new neutral gauge boson $Z^{\prime}$, with a high invisible branching ratio, and a heavy Majorana neutrino production through the decay $Z^{\prime} \rightarrow N +\bar ν$. This result is compared with heavy Majorana production through heavy pair production and the consequent same-sign dilepton production. The other important consequence of the mirror model is the prediction of the Higgs mass. A particular solution leads to a Higgs in the same region as in the standard model. There is, however, another natural solution where the Higgs mass is above 400 GeV.
