Electromagnetic properties of the T+cc molecular states
Abstract
In this work, we discuss the electromagnetic properties of the S-wave and D-wave T+cc molecular states, which include the magnetic moments, transition magnetic moments and radiative decay widths. According to our results, the magnetic moment of T+cc state observed experimentally is -0.09μN. Meanwhile, we also discuss the relations between the transition magnetic moments of the S-wave T+cc molecular states and the radiative decay widths, and we analyze the proportionality between the magnetic moments of the T+cc molecular states. These results provide further information on the inner structure of T+cc molecular states and deepen the understanding of electromagnetic properties of doubly charmed tetraquarks.
