论文摘要
标准模型是一种成功的理论，但缺乏中微子质量产生的机制以及解决自然问题的解决方案。在提议同时解决这两个问题的模型中，通常会预测重大的主要中微子和顶级合作伙伴可以导致由重型Majorana Neutrinos介导的新衰减模式：$ t \ to b \ to B \ to b \，w^{+} \ to b \ ell^e el \ ell^{+} {+} {+} {+} \ ell^eell^}在本文中，我们将通过顶级合作伙伴$ pp \ to t \ bar {t} \至2b+ \ ell^\ pm \ ell^\ ell^\ pm+ 4j $以模型独立的方式研究这种新签名的可观察性。通过执行蒙特 - 卡洛模拟，我们提出了顶级合作伙伴质量的$2σ$排除限制，并在HL-LHC处进行混合参数。
The Standard Model is a successful theory but lack of a mechanism for neutrino mass generation as well as a solution to the naturalness problem. In the models that are proposed to simultaneously solve the two problems, heavy Majorana neutrinos and top partners are usually predicted that can lead to a new decay mode of the top partner mediated by the heavy Majorana neutrinos: $T\to b\,W^{+}\to b\,\ell^{+}\ell^{+}q\bar{q'}$. In this paper, we will study the observability of such a new signature via the pair production process of top partner $pp \to T\bar{T} \to 2b+ \ell^\pm \ell^\pm+4j$ in a model independent way. By performing Monte-Carlo simulation, we present the $2σ$ exclusion limits of the top partner mass and mixing parameters at the HL-LHC.
