Sažetak
We analyze B -> K H_c (where H_c = eta_c, J/psi, chi_{; ; ; cJ(J=0, 1)}; ; ; ) decays estimating nonfactorizable contributions from the light-cone sum rules (LCSR). Nonfactorizable contributions are sizable for B -> K J/psi and particularly for B -> K chi_{; ; ; c1}; ; ; decay. For the B decays into a (pseudo)scalar charmonia we find small nonfactorizable contributions which cannot accommodate relatively large branching ratios obtained by measurements. This specially concerns the puzzling B -> K chi_{; ; ; c0}; ; ; decay.
