Electromagnetic properties of the P<sub>c</sub> (4312) pentaquark state
U. Özdem
Abstract
Abstract Using the light-cone QCD sum rules, we evaluate the magnetic moment of the pentaquark state by considering both the molecular and diquark-diquark-antiquark state, with quantum numbers . In the calculations, we use the diquark-diquark-antiquark and molecular form of the interpolating currents for the pentaquark and the distribution amplitudes of the photon. The numerical results for the magnetic moment obtained using the two different pictures are quite different from each other, which can be used to pin down the underlying structure of . Any experimental measurement of the magnetic moment in the near future will provide an understanding of the internal structure of this pentaquark state.
