\begin{document}$ t\bar{t}$\end{document}) pair production. Beyond enabling high-precision measurements of the Standard Model (SM), CEPC-360 GeV is uniquely positioned to perform searches for new physics beyond the SM (BSM), serving as a valuable complement to hadron colliders. This paper presents a sensitivity study on the direct pair production of staus and smuons at the CEPC with \begin{document}$ \sqrt{s}$\end{document} = 360 GeV, conducted via full Monte Carlo simulation. Under the assumptions of 1.0 ab−1 integrated luminosity and a flat 5% systematic uncertainty, CEPC-360 GeV could potentially discover the combined production of left-handed and right-handed staus up to a mass of 170 GeV (if they exist) or up to 169 for pure left-handed staus and 162 GeV for pure right-handed staus. For direct smuon production, the discovery potential reaches up to 178 GeV under the same conditions."> Search potential for direct slepton pair production at the CEPC with <inline-formula><tex-math id="M1">\begin{document}${ \sqrt{\boldsymbol s}}$\end{document}</tex-math></inline-formula> = 360 GeV -
