论文摘要
提议带有质量中心能量$ \ sqrt {s} $ = 240 GEV作为Higgs工厂的圆形电子正电子对撞机（CEPC），而它也可以为较低能量的新物理搜索提供良好的机会，而在Hadron coller中很难在Hadron Colliders中进行良好的搜索，但在某些理论模型中均可通过诸如Deardeard Iteardeard Iteard Ithard Iteard Iteard Iteard Iteard Itherics。本文使用Full Monte Carlo（MC）模拟了CEPC直接STAU / SMUON生产的灵敏度研究。通过假设扁平5％的系统不确定性，CEPC有可能发现存在左手和右手的左手和右手stau的产生，最高为116 GEV，或者最高为113 GEV，以生产纯净的左手 /右手使用的STAU；直接Smuon的发现潜力以相同的假设达到117 GEV。由于在这项研究中对重建和检测器几何形状的系统不确定性和对探测器的几何形状的依赖有限，因此可以将结果用作在接近240 GEV的其他电子正电子围栏中类似搜索的参考，例如接近240 GEV，例如未来的循环collider $ e^{+e^{+} e^{+} e^{ - } { - fcc-（fcc-ee）和International collider（in International）。
The Circular Electron Positron Collider (CEPC) with a center-of-mass energy $\sqrt{s}$ = 240 GeV is proposed to serve as a Higgs factory, while it can also provide good opportunity for new physics searches at lower energy, which are difficult in hadron colliders but well-motivated by some theory models such as dark matter. This paper presents the sensitivity study of direct stau / smuon production at CEPC using full Monte Carlo (MC) simulation. With the assumption of flat 5% systematic uncertainty, the CEPC has the potential to discover the production of combined left-handed and right-handed stau up to 116 GeV if exists, or up to 113 GeV for the production of pure left-handed / right-handed stau; the discovery potential of direct smuon reaches up to 117 GeV with the same assumption. Due to the conserved assumption of systematic uncertainty and limited reliance on the reconstruction and detector geometry in this study, the results can be used as reference for similar searches in other electron positron colliders at a center-of-mass energy close to 240 GeV, such as Future Circular Collider $e^{+}e^{-}$ (FCC-ee) and the International Linear Collider (ILC).
