Electromagnetic properties of \(\Omega _{c}^0\) resonances via light-cone QCD
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 \(\Omega _c\) states observed by the LHCb Collaboration, we study the electromagnetic properties of the \(\Omega _c\) states as the compact diquark-diquark-antiquark pentaquarks with both \(J^P = \frac{1}{2}^-\) and \(J^P = \frac{3}{2}^-\) 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 \(\Omega _c\) states can reflect their inner structures, which can be used to distinguish their spin-parity quantum numbers. Measuring the magnetic moment of the \(\Omega _c\) states in future experimental facilities can be very helpful for understanding the internal organization and identifying the quantum numbers of these states.
