Properties of the B_{C} System
  I summarize a comprehensive account of the energies, splittings and electromagnetic decays of the low-lying states of the bottom charmed meson system. Richardson's potential is used to include running coupling constant effects in the central potential, and the full radiative one-loop expressions derived by Pantaleone, Tye and Ng are used for the spin-dependent potentials. Our result for the ground state energy is 6286 +15 -6 MeV. The ground state lifetime is found to be 0.36 + 0.05 - 0.05 ps. Both of these numbers are consistent with the measured values recently announced by the CDF collaboration at Fermilab.
