论文摘要
我们对生产的预测和衰减为$ x（2900）$及其可能的充电合作伙伴，分别是$ b^+$和$ b^0 $衰减，考虑到各州的许多竞争模型，包括由Quark Exchange或Pion Exchange介导的三角图，以及包括分子和Tetraquarks的共振风景。假设只有同胞素对称性和颜色偏向的弱衰变的主导地位，我们发现不同模型预测的特征差异。因此，未来的实验研究可以区分国家的竞争解释。
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.
