摘要：

We use the QCD sum rules for an evaluation of the masses of light-and-heavy mesons and their decay constants in the limit of a large heavy quark mass m(Q), finding both the leading terms and the O(1/m(Q)) corrections. The results are summarised and compared to those of other authors in fig. 2.
