Ratio of the color suppressed decays Λ < inf > b < /inf > →ΛJ/ψ and B < sup > 0 < /sup > →KJ/ψ

Abstract

Based on the factorization approximation, we have estimated the ratio of the branching fractions for the color suppressed nonleptonic decays Λb→ΛJ/ψ and B0→KJ/ψ. Treating the s-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.
