我们期待的前景，检测轻玻色子，$X$，在拟议的Z工厂假设生产10 ^{12}$ Z玻色子。如此大的产额是在未来FCC-ee和CEPC对撞机的设计目标之内。具体来说，我们看看的情况下，$X$要么是一个单重标量与标准模型希格斯混合或矢量玻色子与质量1\lesssim M_X \lesssim 80$ GeV。我们发现，有几个渠道是特别有前途的发现前景。特别是$Z\rightarrow f \bar{f} X$和$Z \rightarrow V_Q X$给出了一个非常干净的标准模型背景之上的有希望的信号。我们还讨论了几个通道，有太大的背景是有用的。
We look at the prospects for detecting light bosons, $X$, at proposed Z factories assuming a production of $10^{12}$ Z bosons. Such a large yield is within the design goals of future FCC-ee and CEPC colliders. Specifically we look at the cases where $X$ is either a singlet scalar which mixes with the standard model Higgs or a vector boson with mass $1\lesssim M_X \lesssim 80$ GeV. We find that several channels are particularly promising for discovery prospects. In particular $Z\rightarrow f \bar{f} X$ and $Z \rightarrow V_Q X$ gives a promising signal above a very clean standard model background. We also discuss several channels that have too large a background to be useful.
