摘要:

最近的模拟研究表明,只要能首先发现一种新的中性规范玻色子$Z^{\prime}$,就有可能在未来的高光度LHC运行中发现右手中微子。在这种情况下,当$Z^{\prime}$在大型强子对撞机共振产生时,它随后衰变成质量高达TeV的右手中微子对。然后,这些中微子的衰变留下的签名三轻子最终状态和/或相同符号的双μ子和助推双玻色子。在标准模型的阿贝尔规范扩展中,通过这种机制发现右手中微子的前景得到了发展。在这项工作中,我们研究的过程中涉及的发现机制的框架内的3-3-1模型。

英文摘要:

Recent simulation studies indicate that right-handed neutrinos may be discovered at future high luminosity LHC runs as long as a new neutral gauge boson, $Z^{\prime}$, have been discovered first. In this case, when $Z^{\prime}$ is resonantly produced at the LHC it, subsequently, decays into pair of right-handed neutrinos with mass up to TeV scale. Then the decay of these neutrinos leave as signature tri-lepton final states and/or same-sign di-muon and a boost di-boson. The prospect of discovering right-handed neutrinos through this mechanism has been developed within abelian gauge extension of the standard model. In this work we study the processes involved in this discovery mechanism within the framework of the 3-3-1 model.
