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 mu Pcs = 0.34 +/- 0.12 mu N for the Pcs(4338) state, and mu Pcs= -1.67 +/- 0.58 mu N 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 mu Pcs = 0.63 +/- 0.21 mu N and mu Pcs = -3.33 +/- 1.04 mu N 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.(c) 2022 The Author(s). Published by Elsevier B.V.
