Magnetic dipole moments of the ${\Omega }_c(3185{)}^0$ and ${\Omega }_c(3327{)}^0$ states from molecular perspective

Abstract

In this paper we study the magnetic dipole moments of the newly discovered ${\Omega }_c(3185{)}^0$ and ${\Omega }_c(3327{)}^0$, assuming that ${\Omega }_c(3185{)}^0$ and ${\Omega }_c(3327{)}^0$ are $S$-wave $D\Xi$ and $D^{\ast }\Xi$ molecular pentaquark states, respectively. Together with these states, the magnetic dipole moments of possible $D_s\Xi$, $D_s^{\ast }\Xi$, $D{\Xi }^{\ast }$, and $D_s{\Xi }^{\ast }$ pentaquark states are also studied. The magnetic dipole moments of these singly-charmed pentaquarks are estimated within the framework of the QCD light cone sum rules utilizing the photon distribution amplitudes. In the search for the properties of singly-charmed molecular pentaquark states, the results obtained for the magnetic dipole moments can be useful.
