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.

使用光锥 QCD 和规则，我们通过考虑分子和二夸克-二夸克-反夸克状态以及量子数来评估五夸克状态的磁矩。在计算中，我们使用二夸克-二夸克-反夸克和五夸克内插电流的分子形式和光子的分布幅度。使用两张不同图片获得的磁矩的数值结果彼此完全不同，可以用来确定. 在不久的将来对磁矩的任何实验测量都将提供对这种五夸克状态内部结构的理解。
