Probing single stop production at future 100 TeV hadron collider

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 and mono-bottom channel of the single stop production at the 100 TeV hadron collider, such as the 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 3.2 TeV (1.8 TeV) by the mono-top channel (mono-bottom channel) at $5\sigma$ level. Exclusion limits on stop mass and higgsino mass parameter $\mu$ are also presented for both channels.
