Investigation on the electromagnetic properties of the $ D(*) Σ_c(*)$ molecules

We systematically explore their electromagnetic characteristics to improve our understanding of the quark-gluon dynamics underlying the complex and controversial nature of multiquark systems. In this study, the magnetic dipole moments of D Σc, D Σc* and D* Σc doubly-charmed pentaquarks are extracted, which are directly related to the inner organization of the relevant states. The magnetic dipole moments of these states have been evaluated employing the QCD light-cone sum rules technique with isospin spin-parity I(JP) = 1/2(1/2⁻), I(JP) = 1/2(3/2⁻) and I(JP) = 1/2(3/2⁻), for D Σc, D Σc* and D* Σc doubly-charmed pentaquarks respectively. Our predictions for the magnetic dipole moment μDΣc = 2.98+0.76-0.54~μN for the D Σc pentaquark, μDΣc^* = 1.65+0.45-0.34~μN for the DΣc^* pentaquark, and μD^*Σc = -3.63+0.79-0.60~μN for the D^*Σc pentaquark. Furthermore, we have also extracted the electric quadrupole and the magnetic octupole moments of the D Σc* and D* Σc doubly-charmed pentaquarks. These values show a non-spherical charge distribution. As a by-product, the magnetic dipole moments of the isospin-3/2 partners associated with these doubly-charmed pentaquarks have also been determined. The magnetic dipole moments are calculated as follows: μDΣc = 3.78+0.94-0.70~μN, μDΣc^* = 2.08+0.57-0.43~μN, μD^*Σc = -4.59+0.99-0.76~μN for the isospin-3/2 partners D Σc, D Σc* and D* Σc doubly-charmed pentaquarks, respectively.
