Abstract
We systematically examined the mass spectra and their two-body hadronic decays of the beauty-charm meson family considering coupled channel effects. Our results can effectively explain the observed meson spectrum, and the prediction of the mass spectrum for unobserved beauty-charm mesons can be tested in future experiments. Compared with previous studies, we systematically examine the beauty-charm meson family within the coupled channel components. The state in beauty-charm meson family has few percent of coupled channel component, while the , , and states have more than ten percent of coupled channel component. The two-body hadronic decay widths of the state is as narrow as 3 MeV. The two-body hadronic decay widths of , , , , , and are approximately 109, 67, 60, 57, 201, and 76 MeV, respectively. Furthermore, the mixing effects between and states are discussed.
