| contents | 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 Σ_c$, $ D Σ_c^{*}$ and $ D^{*} Σ_c$ 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 $\rm{I(J^P)} = \frac{1}{2}(\frac{1}{2}^-)$, $\rm{I(J^P)} = \frac{1}{2}(\frac{3}{2}^-)$ and $\rm{I(J^P)} = \frac{1}{2}(\frac{3}{2}^-)$, for $ D Σ_c$, $ D Σ_c^{*}$ and $ D^{*} Σ_c$ doubly-charmed pentaquarks respectively. Our predictions for the magnetic dipole moment $μ_{DΣ_c} = 2.98^{+0.76}_{-0.54}~μ_N$ for the $ D Σ_c$ pentaquark, $μ_{DΣ_c^*} = 1.65^{+0.45}_{-0.34}~μ_N$ for the $DΣ_c^*$ pentaquark, and $μ_{D^*Σ_c} = -3.63^{+0.79}_{-0.60}~μ_N$ for the $D^*Σ_c$ pentaquark. Furthermore, we have also extracted the electric quadrupole and the magnetic octupole moments of the $ D Σ_c^{*}$ and $ D^{*} Σ_c$ doubly-charmed pentaquarks. These values show a non-spherical charge distribution. We hope that our predictions of the magnetic dipole moments of the doubly-charmed pentaquarks, in conjunction with the results of other theoretical investigations of the spectroscopic parameters and decay widths of these intriguing pentaquarks, will prove valuable in the search for these states in future experiments and in elucidating the internal structure of these pentaquarks. |
