论文摘要
我们采用低能最小超对称标准模型(MSSM)来探索与$ z $ - pele和higgs-pole溶液相关的参数空间。这样的参数空间不仅可以饱和,因此在Planck 2018设置的5 $σ$内结合的冷暗物质遗物密度,而且还满足其他标准对撞机的质量界限和B物理界。特别是,我们表明右撇子Selectron可以很轻。因此,我们建议在未来的Lepton碰撞中搜索相对重的右撇子Selectron与质量中心的能量$ \ sqrt {s} = 240 $ GEV和集成的发光度3000 $ \ rm {fb^{ - 1}}} $ via Mono-Photon Channel: e^{ - } _ {r} \ rightarrow {\ tildeχ_{1}^{0}(bino)}+{\tildeχ_{1}^{0}^{0} {0}(bino)}+γ$。我们表明,对于$ z $ - peL的情况,右手选择的Selectron将在3 $σ$和2 $σ$时分别排除在180 GEV和210 GEV,而右手Selectry将分别排除最多140 GEV和180 GEV和180 GEV,在3 $σ$和2 $σ$中,在Higgs-Pole中,将分别排除在3 $σ$和2 $σ$中。
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 5$σ$ set 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 $\sqrt{s}=240$ GeV and integrated luminosity 3000 $\rm{fb^{-1}}$ via mono-photon channel: $e^{+}_{R} e^{-}_{R}\rightarrow {\tilde χ_{1}^{0}(bino)}+{\tilde χ_{1}^{0}(bino)}+γ$. We show that for the $Z$-pole case the right-handed selectron will be excluded up to 180 GeV and 210 GeV respectively at 3$σ$ and 2$σ$, while the right-handed selectron will be excluded up to 140 GeV and 180 GeV respectively at 3$σ$ and 2$σ$ in case of Higgs-pole.
