Strong decays of the Pc(4312) and its isospin cousin via the QCD sum rules
CHINESE PHYSICS C(2024)
Abstract
In the present work, considering the conservation of isospin in the strong decays, we investigate the strong decays of the pentaquark molecule candidate P-c(4312) and its possible higher isospin cousin P-c(4330) in the framework of the QCD sum rules. What's more, the pole residue of the Delta baryon with isospin eigenstate |II3 >=|3/2 1/2 > is obtained. If the possible pentaquark molecule candidate P-c(4330) could be testified in the future experiment, it would shed light on interpretations of the P(c )states.
