摘要：
The leptonic decay constant and the mass of the B(c)-meson are estimated using two versions of QCD sum rules. The predictions take into account the uncertainties due to the variations of the continuum threshold within the stability regions. Our optimal results are: f(B(c)) = 300 +/- 65 MeV and M(B(c)) = 6.25 +/- 0.20 GeV.
