The spin-averaged B_c spectrum is obtained in a Cornell potential by anchoring the 1S state to experiment, scanning the string tension and Coulomb strength, and using VMC-GFMC to predict higher states that match data within tens of MeV.

abstract
A fully reconstructed Bc --> Jpsi Pi signal is observed with the D0 detector at the Fermilab Tevatron p-pbar collider. Using 1.3 inverse femtobarns of integrated luminosity, the signal is extracted with a significance more than five standard deviations above background. The measured Bc meson mass is 6300 (+-) 14 (stat) (+-) 5 (sys) MeV/cc

Spin-averaged $B_c$ Spectrum in a Cornell-type Potential Using VMC Baseline and GFMC Evolution
The spin-averaged B_c spectrum is obtained in a Cornell potential by anchoring the 1S state to experiment, scanning the string tension and Coulomb strength, and using VMC-GFMC to predict higher states that match data within tens of MeV.
