Magnetic moment of the ${\Xi }_b(6227)$ as a molecular pentaquark state

Abstract

In this study, considering that the ${\Xi }_b(6227)$ state is in molecular structure, the magnetic moment of this state is extracted in the light-cone QCD sum rules. The numerical result is obtained as ${\mu }_{{\Xi }_b}=0.12\pm 0.03{\mu }_N$. The magnetic moment of this state contains important information of its internal structure and shape deformations. Measurement of the magnetic moment of the ${\Xi }_b(6227)$ state in future experimental facilities can be very helpful in identification of the quantum numbers, as well as comprehension of the inner structure of this state.
