论文摘要
Top Squark（停止）是超对称模型（SUSY）的关键部分，以了解自然性问题。除了传统的停止对生产外，通过Electroweak互动的单个生产提供了具有独特特征的信号，可以帮助确认顶部的壁cark的存在。在本文中，我们在简化的最小超对称标准模型（MSSM）中调查了未来质子 - 普罗顿山脉FCC-HH和SPPC的单个停止产生的单顶通道的可观察性。使用3000 $ \ text {fb}^{ - 1} $的集成发光度，我们可以通过单顶通道的质量探测质量为3.25 tev的停车，以$5σ$级别。考虑到10％的系统不确定性，可以在约1.5 TEV达到停止质量的排除限制。还提出了停止质量和希格斯诺质量参数$μ$的排除限制。
Top squark (stop) is a crucial part of supersymmetric models (SUSY) to understand the naturalness problem. Other than the traditional stop pair production, the single production via electroweak interaction provides signals with distinctive features which could help confirm the existence of the top squark. In this paper, we investigate the observability of stop through the mono-top channel of the single stop production at the future proton-proton colliders, FCC-hh and SPPC, in a simplified Minimal Supersymmetric Standard Model (MSSM). With the integrated luminosity of 3000 $\text{fb}^{-1}$, we can probe the stop with mass up to 3.25 TeV by the mono-top channel at $5σ$ level. Considering the systematic uncertainty of 10%, the exclusion limit for stop mass can be reached at about 1.5 TeV. Exclusion limits on stop mass and higgsino mass parameter $μ$ are also presented.
