论文摘要
已经提出了超越标准模型的模型，以同时解决自然性和中微子质量的问题，其中通常预测重型主要中微子和类似媒介的顶级伴侣。因此，可以出现由重的Majorana Neutrino介导的顶级合作伙伴的新衰减通道：$ t \ to b \，w^{+} \ to B \，\ ell^{+} {+} \ ell^{+} q \ bar {q'} $。我们在本文中研究了通过在14 TEV LHC上单次生产的衰减过程的可观察性：$ pp \ to t/\ bar {t} $+jets $ \ to b/\ bar {b}+μ^{\ \ \ pm}μ^{\ pm pm pm} $+jets。顶级合作伙伴质量上的$2σ$排除界和混合参数由蒙特卡洛模拟给出，蒙特 - 卡洛模拟超过了搜索中的VLT对生产的质量范围$ m_ {t}> 1.3 $ tev。
Models beyond the Standard Model have been proposed to simultaneously solve the problems of naturalness and neutrino mass, in which heavy Majorana neutrinos and vector-like top partners are usually predicted. A new decay channel of the top partner mediated by the heavy Majorana neutrino can thus appear: $T\to b\,W^{+}\to b\,\ell^{+}\ell^{+}q\bar{q'}$. We study in this paper the observability of this decay process through single production of the top partner at the 14 TeV LHC: $pp\to T/\bar{T}$+jets$\to b/\bar{b}+μ^{\pm}μ^{\pm}$+jets. $2σ$ exclusion bounds on the top partner mass and mixing parameters are given by Monte-Carlo simulation, which surpass those from the search through VLT pair production in the mass range of $m_{T}>1.3$ TeV.
