Analysis of the 32± pentaquark states in the diquark-diquark-antiquark model with QCD sum rules

In this article, we construct the axialvector-diquark-scalar-diquark-antiquark type and the axialvector-diquark-axialvector-diquark-antiquark type interpolating currents, and study the JP=32± hidden-charm pentaquark states with the strangeness S=0,−1,−2,−3 systematically using the QCD sum rules. The predicted masses of the pentaquark states Puud1012(32−), Puud1112(32−) and Puud1132(32−) are compatible with the experimental value MPc(4380)=4380±8±29 MeV from the LHCb collaboration, more experimental data are still needed to identify the Pc(4380) unambiguously.
