超对称性（SUSY）可能是标准模型（SM）最受欢迎的扩展之一，但到目前为止，在LHC还没有观察到超对称性粒子的证据。一个明显的问题是，它们是否已经出现，但逃脱了我们的检测，或者它们是否根本不存在。我们认为，未来的ILC可能提供足够的能量和光度来产生超对称粒子，只要它们不是太重。超味对称性将超对称介子的产生率与常规介子的产生率联系在一起，因为两者都包含一个重组分和一个轻组分。在这项工作中，我们估计的SUSY介子的生产率附近的生产阈值，并比较它与BB生产。我们的分析表明，如果质量低于10 s/2（10 s是ILC能量）的超对称介子存在，它们可以在未来的ILC甚至中国的CEPC中观察到。
Supersymmetry (SUSY) may be one of the most favored extensions of the Standard Model (SM), but so far at the LHC no evidence of SUSY particles has been observed. An obvious question is whether they have already emerged but escaped our detection, or whether they do not exist at all. We propose that the future ILC may provide sufficient energy and luminosity to produce SUSY particles as long as they are not too heavy. Superflavor symmetry associates production rates of SUSY mesinos with those of regular mesons, because both contain a heavy constituent and a light one. In this work, we estimate the production rate of SUSY mesinos near their production threshold and compare it with BB production. Our analysis indicates that if SUSY mesinos with masses below √s/2 (√s is the ILC energy) exist, they could be observed at the future ILC or even the proposed CEPC in China.
