论文摘要
搜索顶级蹲下（停止）是测试Susy自然性的关键任务。与停止对生产不同，单一停止生产依赖于其电动性特性，并且可以提供一些独特的特征。在单个生产过程之后，$ pp \ to \ tilde t_1 \tildeχ^ - _ 1 \ to t \tildeχ^0_1 \tildeχ^-_ 1 $，顶部的Quark具有两个衰减通道：Leptonic Channel和Hadronic Channel和Hadronic Channel。在本文中，我们在简化的MSSM方案中探测了这两个通道的可观察性。我们发现，在27个TEV LHC上，集成的光度为$ {\ cal l} = 15〜 \ text {ab}^{ - 1} $，$ m _ {\ tilde {\ tilde {t} _1} _1} <1900 $ gev和$μ<750 $ gev可以在$2σ$ noo noo中排除， $ m _ {\ tilde {t} _1} <1200 $ gev和$μ<350 $ gev可以通过hadroonic频道以$2σ$排除。
Searching for the top squark (stop) is a key task to test the naturalness of SUSY. Different from stop pair production, single stop production relies on its electroweak properties and can provide some unique signatures. Following the single production process $pp \to \tilde t_1 \tildeχ^-_1 \to t \tildeχ^0_1 \tildeχ^-_1$, the top quark has two decay channels: leptonic channel and hadronic channel. In this paper, we probe the observability of these two channels in a simplified MSSM scenario. We find that, at the 27 TeV LHC with the integrated luminosity of ${\cal L} = 15~\text{ab}^{-1}$, $m_{\tilde{t}_1}<1900$ GeV and $μ<750$ GeV can be excluded at $2σ$ through the leptonic mono-top channel, while $m_{\tilde{t}_1}<1200$ GeV and $μ<350$ GeV can be excluded at $2σ$ through the hadronic channel.
