基于QCD或强子相互作用的各种理论计算预测，除了最近观察到的I(J·P)=0(3+)的双重子共振d⁎(2380)之外，还应该存在镜像量子数I(J·P)=3(0+)的双重子共振。我们在这里报告了在 p p→ p p π+ π+ π− π− 反应的数据中寻找这种神经网络解耦状态的情况。由于没有找到明确的证据，我们给出了质量范围 2280-2500 MeV 内这种共振的产生截面的上限。
Various theoretical calculations based on QCD or hadronic interactions predict that in addition to the recently observed dibaryon resonance d⁎(2380) with I (J P)= 0 (3+) there should also exist a dibaryon resonance with mirrored quantum numbers I (J P)= 3 (0+). We report here on a search for such a NN-decoupled state in data on the p p→ p p π+ π+ π− π− reaction. Since no clear-cut evidence has been found, we give upper limits for the production cross section of such a resonance in the mass range 2280–2500 MeV.
