摘要

在本研究中，考虑到强衰变中的等空素守恒，我们在 QCD 和规则的框架内研究了候选五夸克分子的强衰变及其可能的高等空素表亲。此外，我们还得到了具有等空素特征态的Δ重子的极残差。如果能确定可能的候选五夸克分子，将有助于在未来的实验中解释这些态。

Strong decays of the P c(4312) and its isospin cousin via the QCD sum rules* * Supported by the National Natural Science Foundation (12175068) and the Fundamental Research Funds for the Central Universities of China

In this study, considering the conservation of isospin in the strong decays, we investigate the strong decays of the pentaquark molecule candidate

and its possible higher isospin cousin

in the framework of the QCD sum rules. Further, the pole residue of the Δ baryon with isospin eigenstate

is obtained. If the possible pentaquark molecule candidate

could be determined, it would shed light on the interpretations of the

states in future experiments.
