Abstract

We systematically study the electromagnetic properties of controversial states whose internal structure is not elucidated and we try to offer a different point of view to unravel the internal structure of these states. Inspired by the Ω_c states observed by the LHCb Collaboration, we study the electromagnetic properties of the Ω_c states as the compact diquark-diquark-antiquark pentaquarks with both J^P = (1)/(2)^- and J^P = (3)/(2)^- in the context of the QCD light-cone sum rule model. From the obtained numerical results, we conclude that the magnetic dipole moments of the Ω_c states can reflect their inner structures, which can be used to distinguish their spin-parity quantum numbers. Measuring the magnetic moment of the Ω_c states in future experimental facilities can be very helpful for understanding the internal organization and identifying the quantum numbers of these states.
