B-C SPECTROSCOPY IN A QUANTUM-CHROMODYNAMIC POTENTIAL MODEL

We have investigated B-c spectroscopy with the use of a quantum-chromo dynamic potential model which was recently used by us for the light-he avy quarkonia. We give our predictions for the energy levels and the E 1 transition widths. We also find, rather surprisingly, that although B-c is not a light-heavy system, the heavy quark effective theory with the inclusion of the m(b)(-1) and m(b)(-1)lnm(b) corrections is as su ccessful for B-c as it is for B and B-s.
