论文摘要
NA64实验由两个检测器组成，这些探测器计划位于电子（Na64e）和Muon（Na64 $μ$）的cern sps的光束，并在2021年LHC长期2之后开始操作，主要目标是搜索黑暗扇形物理学 - 尤其是peactible and Invible and Invible and Invible and Invible and Invible and Invible and Invible and Invible and Invible and Invible and Invilles（$ a peactible）（$ a Dive and Al o a $ a $ a $ a'$ a $ a $ a $ a $ a $ a $ a $ a' $^8 $ be和$g_μ-2$异常。在这里，我们回顾了这些物理目标，即NA64的当前状态，包括最新的结果和进一步搜索的观点，以及该领域的其他正在进行的或计划的实验。 LDM上的主要理论结果，$γ-A'U搅拌项的起源问题及其与环校正的连接，还讨论了可能存在新的光$ z'$耦合到$l_μ-l_τ$当前的问题。
The NA64 experiment consists of two detectors which are planned to be located at the electron (NA64e) and muon (NA64$μ$) beams of the CERN SPS and start operation after the LHC long-stop 2 in 2021. Its main goals include searches for dark sector physics - particularly light dark matter (LDM), visible and invisible decays of dark photons ($A'$), and new light particles that could explain the $^8$Be and $g_μ-2$ anomalies. Here we review these physics goals, the current status of NA64 including recent results and perspectives of further searches, as well as other ongoing or planned experiments in this field. The main theoretical results on LDM, the problem of the origin of the $γ-A'$ mixing term and its connection to loop corrections, possible existence of a new light $Z'$ coupled to $L_μ-L_τ$ current are also discussed.
