Radiative decays and magnetic moments of the predicted Be-like molecules

In this work, we first perform a systematic study of the transition magnetic moments and the corresponding radiative decay behaviors of the Bc-like molecular states associated with their mass spectra, where the constituent quark model is adopted by considering the S -D wave mixing effect. Our numerical results show that the radiative decay properties can be considered as the effective physical observable to reflect the inner structures of these Bc-like molecular states. Meanwhile, we also discuss the magnetic moments of the Bc-like molecular states, and we find that the magnetic moment properties can be used to distinguish the Bc-like molecular states from the conventional Bc mesonic states, which have the same quantum numbers and similar masses. We expect that the present study can inspire the interest of the experimentalist in exploring the electromagnetic properties of the Bc-like molecular states, especially the radiative decay properties.

Automated summary

In this study, we systematically investigate the transition magnetic moments and radiative decay behaviors of Bc-like molecular states with different mass spectra. Our findings suggest that the radiative decay properties and magnetic moment properties can be used as effective observables to reflect the inner structures of these states.
