摘要：
We estimate the non-leptonic B decays B --> (psi, psi', chi1c) + K(i). where K(i) are various K-meson resonances. We use the model of Isgur, Wise, Scora and Grinstein in the context of heavy quark effective theory, to calculate the hadronic matrix elements. Our estimates show that a substantial fraction of B --> X(s)psi results in higher resonances of K-meson and besides B --> K(K*)psi, a considerable fraction of B --> X(s)(ccBAR) goes to B --> (K, K*) + (psi', chi1c).
