标题： LEP $e^{+}\,e^{-}\,\rightarrow\,μ^{+}\, μ^{-}\,γ\,γ$ events and their consequences at future $e^+e^-$ colliders

摘要： $e^{+}\,e^{-}\,\rightarrow\,l^{+}\, \l^{-}\,\gamma\,\gamma$异常事件，由$L3$探测器在$e^+ e^-$ $CERN-LEP$ 对撞机上探测到，已经进行了分析。 已经表明，将这些事件解释为质量为 60 GeV 的标量（赝标量）共振现象与其他实验数据相矛盾。 如果这种共振确实存在，已在未来$e^+e^-$对撞机的某些过程中发现它的前景进行了讨论。 显示英文摘要

摘要： The $e^{+}\,e^{-}\,\rightarrow\,l^{+}\, \l^{-}\,\gamma\,\gamma$ anomalous events, detected by $L3$ de\-tec\-tor at $e^+ e^-$ $CERN-LEP$ collider have been analysed. It has been shown that the interpretation of such events as a manifestation of scalar (pseudoscalar) resonance with the mass of 60 GeV contradicts other experimental data. In case of a possible existence that kind of resonance, the perspectives to discover one in some processes at future $e^+e^-$ colliders have been discussed.
