Revealing the nature of Ωc-like states from pentaquark perspective

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 Ωc states observed by the LHCb Collaboration, we study the electromagnetic properties of the Ωc-like states as the compact diquark-diquark-antiquark pentaquarks with both JP = 1/2⁻ and JP = 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 Ωc-like states can reflect their inner structures, which can be used to distinguish their spin-parity quantum numbers. Measuring the magnetic moment of the Ωc-like states in future experimental facilities can be very helpful for understanding the internal organization and identifying the quantum numbers of these states.
