英文摘要	We employ the low energy Minimal Supersymmetric Standard Model (MSSM) to explore the parameter space associated with Z-pole and Higgs-pole solutions. Such parameter spaces can not only saturate the cold dark matter relic density bound within 5sset by the Planck 2018, but also satisfy the other standard collider mass bounds and B-physics bounds. In particular, we show that the right-handed selectron can be light. Thus, we propose a search for the relatively heavier right-handed selectron at the future lepton colliders with the center-of-mass energy root s= 240GeV and integrated luminosity 3000 fb(-1)via the mono-photon channel: e(R)(+)e(R)(-)-> (chi) over tilde (0)(1)( bino)+ (chi) over tilde (0)(1)( bino)+gamma. We show that for the Z-pole case the righthanded selectron will be excluded up to 180 GeV and 210 GeV respectively at 3sand 2s, while the right-handed selectron will be excluded up to 140 GeV and 180 GeV respectively at 3sand 2sin case of Higgs-pole.
