Abstract
In this study, we discuss the magnetic moment of Pcs(4338) and Pcs(4459) hidden-charmed pentaquarks, which are closely related to their substructures. The magnetic moments of these states are calculated with the help of the QCD light-cone sum rules method with quantum numbers I(JP)=0(1/2−) and I(JP)=0(3/2−) for Pcs(4338) and Pcs(4459), respectively. Our predictions for the magnetic moment μPcs=0.34±0.12μN for the Pcs(4338) state, and μPcs=−1.67±0.58μN for the Pcs(4459) state. As a by-product, the magnetic moments of the isospin−1 partners of these states have also been obtained. The magnetic moments are obtained as μPcs=0.63±0.21μN and μPcs=−3.33±1.04μN for the isospin-1 partners of the Pcs(4338) and Pcs(4459) states, respectively. Our results regarding the magnetic moments of these color singlet-singlet type pentaquark states are compared with the results in the literature.
