Description
We apply our Bethe-Salpeter model for mesons to the Bc family with parameters fixed in our previous investigation. We evaluate the mass of the pseudoscalar Bc meson as 6.356 and 6.380 GeV/c2 and the lifetime as 0.47 and 0.46 ps, respectively, in two reductions of the Bethe-Salpeter equation, in good agreement with the recently reported mass of 6.40±0.39 (stat) ±0.13 (syst) GeV/c2 and lifetime of 0.46-0.16+0.18 (stat) ±0.03 (syst) ps by the CDF Collaboration. We evaluate the decay constant of the Bc meson and compare different contributions to its decay width. copyright 1999 The American Physical Society
