我们提出了一个新的反应，从BESIII实验中报道的1830 MeV左右的质量的一个h1共振的互补。新的反应是，或者。利用的分析信息，我们发现这两个H衰变的不变质量分布在1830 MeV附近呈现出一个清晰的峰，与纯相空间的结果完全不同。我们建议实施这些反应，以断言这种难以捉摸的共振的存在，其本质是一个具有0 −（1 + −）量子数的矢量-矢量分子，只耦合到通道。
We present a new reaction, complementary tofrom which anh1resonance with mass around 1830 MeV was reported from a BESIII experiment. The new reaction is, or. Using the information from the analysis of, we find that theinvariant mass distribution for those twoΗdecays exhibits a clear peak around 1830 MeV perfectly distinguishable from what one obtains with pure phase space. We suggest the implementation of these reactions to assert the existence of this elusive resonance which, by its nature as a vector-vector molecule with 0−(1+−) quantum numbers, only couples to thechannel.
