摘要

在未来圆形轻子对撞机（FCC-ee）的未来电弱精度测量的背景下，我们考虑了最近旨在寻找超越标准模型的物理特征的建议。我们特别关注最近关于αem（MZ2）非常精确的直接测量的新建议。结果表明，在10−5阶的精度水平上，暗光子的影响可能非常显著。

Searching for the dark photon at the Future Circular Lepton Collider

In the context of future electroweak precision measurements at the Future Circular Lepton Collider (FCC-ee), we consider recent proposals aimed at finding signatures of physics beyond the Standard Model. In particular, we focus on recent novel suggestions for very precise direct measurements of

α_{em} (M_{Z}^{2})

. It is shown that at a level of precision of order

10^{- 5}

, the effects of a dark photon may be very significant.
