摘要：
A model of the heavy meson, composed of constituent quarks, is considered. It allows one to calculate the semileptonic decay widths of B --> D-(*)e nu and to extract the Kobayashi-Maskawa matrix element \V-bc\ = 0.033 +/- 0.003 from experimental data. The infinitely heavy quark limit is discussed.
