%X 本文研究了在未来正负电子对撞机实验条件下，寻找轻子超对称伴子的物理分析预研。利用计算机产生的基于最小超对称模型和R宇称守恒假设的信号过程样本以及标准模型物理过程样本，并结合国际主流在研的正负电子对撞机的实验参数进行全模拟。结果表明，在考虑5%系统不确定性的前提下，正负电子对撞机可大幅提高现有实验对所研究超对称粒子的发现及排除限，验证了正负电子对撞机在寻找新物理方面的探测能力与前景，也为国际上正在筹备中的各类大型正负电子对撞机提供了重要的物理分析预研和参考。<br />
This paper presents the pre-study of the physical analysis of the search for sleptons under the experimental conditions of future electron-positron colliders. Full simulations are performed by using computer-generated signal process samples based on the minimal supersymmetric standard model and the assumption of R-parity conservation, as well as standard model physics process samples, and combining them with the experimental parameters of mainstream international proposed electron-positron colliders. The results show that considering a 5% systematic uncertainty, the electron-positron colliders can significantly improve the existing experimental limits for the discovery and exclusion of the studied supersymmetric particles. This validates the electron-positron colliders’ capability and prospects in detecting new physics and provides important physical pre-study and reference for various large-scale electron-positron colliders that are being prepared internationally.
