This minireview aim is to outline the main experimental results related to the search for LDM (light dark matter) at NA64 experiment at CERN. We discuss current results and the NA64 perspectives. Also we discuss the problem of the origin of the photon-dark photon mixing term \(\tfrac{\varepsilon }{2}{{F}^{{\mu \nu }}}F_{{\mu \nu }}^{'}\) and its connection with loop corrections.

在NA64实验中寻找光暗物质

这次小型审查的目的是概述与CERN在NA64实验中寻找LDM（浅暗物质）有关的主要实验结果。我们讨论当前的结果和NA64的观点。我们还将讨论光子与暗光子混合项\（\ tfrac {\ varepsilon} {2} {{F} ^ {{\ mu \ nu}}}} F _ {{\ mu \ nu}}的起源问题^ {'} \）及其与循环更正的联系。
