We evaluate the mass of the pseudo-scalar $B_c$ meson as 6.356 GeV/$c^2$ and 6.380 GeV/$c^2$ and the lifetime as 0.47 ps and 0.46 ps respectively in two reductions of the Bethe-Salpeter Equation, in good agreement with the recently reported mass of 6.40 $\\pm$ 0.39 (stat.) $\\pm$ 0.13 (syst.) GeV/$c^2$ and lifetime of $0.46^{+0.18}_{-0.16}$ (stat.) $\\pm$ 0.03 (syst.) ps by the CDF Collaboration. We evaluate the decay constant of the $B_c$ meson and compare different contributions to its decay width.", "revisions": [ { "version": "v1", "updated": "1998-07-02T18:04:20.000Z" } ], "analyses": { "keywords": [ "bethe-salpeter model", "decay width", "cdf collaboration", "decay constant", "bethe-salpeter equation" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
