摘要：
We analyze the decay modes B-0 --> (D*-DK+)-K-0 and B-0 --> (D*-DK+)-K-*0 and, using the available experimental data, we find bounds for the constants g and h describing the strong coupling of heavy mesons to light pseudoscalar mesons. Both the decay channels are dominated by broad L = 1 charm resonances; the dominance is effective also in B-0 --> (D-DK+)-K-0 and B-0 --> (D-DK+)-K-*0. (C) 2002 Elsevier Science B.V.
