Magnetic moment of the ${\Theta }^{+}$ pentaquark state

We calculate the magnetic moment of the recently observed ${\Theta }^{+}$ pentaquark state in the framework of the light cone QCD sum rules using the photon distribution amplitudes. We find that ${\mu }_{{\Theta }^{+}}=(0.12\mathrm{}\pm 0.06){\mu }_N,$ which is quite small. We also compare our result with predictions of other groups.
