摘要：

We calculate the spectrum of the charm-beauty mesons using the relativized quark model. Using the wave functions from this model we compute the radiative widths of excited c (b) over bar states. The hadronic transition rates between c (b) over bar states are estimated using the Kuang-Yan approach and are combined with the radiative widths to give estimates of the relative branching ratios. These results are combined with production rates at the Tevatron and the LHC to suggest promising signals for excited B-c states. Our results are compared with other models to gauge the reliability of the predictions and point out differences.
