论文摘要
我们通过CMD-3实验对$ E^+e^ - $ nihihations获得的精确数据分析了$ ϕ $ peacs附近的两个带电的Kaons。仅当假定反应阈值以下的真实轴上的杆上，才能获得完美的拟合。这可以解释为Kaonium 2p状态的存在的证明，Kaonium是$ k^+$和$ k^ - $的化合物。关于同一过程的Babar协作数据支持了这一结论，此外，还指出了强烈的相互作用作为结合能的主要来源。讨论了在$ e^+e^ - \rightarrowπ^+π^ - $过程中发现2p kaonium的可能性。 $ k^0 $ -ONIUM的2P状态根据CMD-3 $ E^+E^ - \ rightArrow K^0_sk^0_l $ data表示。
We analyze the precise data obtained by the CMD-3 experiment on the $e^+e^-$ annihilation into two charged kaons in the vicinity of the $ϕ$ peak. A perfect fit is obtained only if a pole on the real axis below the reaction threshold is assumed. This can be interpreted as proof of the existence of the 2p state of kaonium, a compound of $K^+$ and $K^-$. The BaBar Collaboration data on the same process supports this conclusion and, in addition, points to the strong interaction as a dominant source of the binding energy. The possibility of discovering 2p kaonium in the $e^+e^-\rightarrow π^+π^-$ process is discussed. The 2p state of $K^0$-onium is indicated on the basis of the CMD-3 $e^+e^-\rightarrow K^0_SK^0_L$ data.
