区分对$X(2900)$状态的解释
Discriminating among interpretations for the $X(2900)$ states
摘要：
我们预测的生产和衰变的$X(2900)$状态，和他们可能的带电的合作伙伴，在$B^+$和$B^0$衰变，考虑到一些竞争模型的状态，包括三角形图介导的夸克交换或π介子交换，和共振的情况下，包括分子和四夸克。假设只有同位旋对称性和优势的颜色有利于弱衰变，我们发现不同的模型的预测特征的差异。因此，未来的实验研究可以区分对状态的竞争性解释。
英文摘要：
We make predictions for the production and decays of $X(2900)$ states, and their possible charged partners, in $B^+$ and $B^0$ decays, considering a number of competing models for the states, including triangle diagrams mediated by quark exchange or pion exchange, and resonance scenarios including molecules and tetraquarks. Assuming only isospin symmetry and the dominance of colour-favoured weak decays, we find characteristic differences in the predictions of the different models. Future experimental studies can therefore discriminate among the competing interpretations for the states.
