abstract
We calculate the spectrum of the charm-beauty mesons using the relativized quark model. Using the wavefunctions from this model we compute the radiative widths of excited c\bar{b} states. The hadronic transition rates between c\bar{b} 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.

A method to extract fs/fd and similar ratios from exclusive semi-leptonic B decays yields a 7% uncertainty constraint using existing measurements.
Bayesian MCMC sampling of Cornell and log-modified Cornell potentials reproduces known B_c states and supplies mass predictions for higher excitations with propagated uncertainties.
