Abstract: | Based on the factorization approximation, we have estimated the ratio of the branching fractions for the color suppressed
nonleptonic decays Λ
b
→ΛJ/ψ andB
0→KJ/ψ. Treating thes-quark as heavy, we have used the HQET to calculate the hadronic matrix elements. The mesonic Isgur-Wise function is calculated
in the quark model whereas for the baryonic IW function we have employed the bound state soliton picture. The results obtained
agree very well with the recent CDF experimental data. |
