Interpretation of $\hat{I}\text{c◯}(2012)$ as a $\hat{I}ž(1530)K$ molecular state

Xiang Yu, Jin-Peng Zhang, Xu-Liang Chen +3

We investigate the mass and strong decay properties of the $\hat{I}\text{c◯}(2012)$ resonance using QCD sum rules, assuming it to be an S-wave $\hat{I}ž(1530)\bar{K}$ molecular pentaquark state with $…
