Magnetic Moment of The ${\Theta }^{+}$ Pentaquark State

Abstract

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