‘真muonium’({u}{sup+}{u}{sup-})和‘true tauonium’({tau}{sup+}{tau}{sup-})束缚态不仅是最重的,而且是最紧凑的纯QED系统。{tau}的快速弱衰变使观测到真正的tauon变得困难。然而,正如我们所展示的,在现代电子-正电子对撞机上生产和研究真正的钚是可能的。
The 'true muonium' ({mu}{sup +}{mu}{sup -}) and 'true tauonium' ({tau}{sup +}{tau}{sup -}) bound states are not only the heaviest, but also the most compact pure QED systems. The rapid weak decay of the {tau} makes the observation of true tauonium difficult. However, as we show, the production and study of true muonium is possible at modern electron-positron colliders.
