摘要：

We have calculated the pseudoscalar decay constants using the relativized quark model. We find fD 24020 MeV, fDs 29020 MeV, fB 15515 MeV, fBs 21020 MeV, and fBc 41040 MeV where the "errors" are our estimates of the reliability of the results. We used these values to study the Cabibbo-Kobayashi-Maskawa matrix elements. In particular, we combined our theoretical estimate of fB with the ARGUS/CLEO result for B0-B0 mixing to study the relation between |Vtd| and the t-quark mass. Recent measurements of Vbc and Vbu constrain mt70 GeV. © 1990 The American Physical Society.
