Neural network study of hidden-charm pentaquark resonances
Chinese Physics C, High Energy Physics & Nuclear Physics
Recently, the LHCb experiment announced the observation of hidden-charm pentaquark states , , and near and thresholds. In this present work, we studied these pentaquarks in the framework of the nonrelativistic quark model with four types of potential. We solved five-body Schrödinger equation by using the artificial neural network method and made predictions of parities for these states, which are not yet determined by experiment. The mass of another possible pentaquark state near the with is also calculated.doi:10.1088/1674-1137/43/9/093103 fatcat:7sbmkre5sbc7lophfywpy3l26q
