| 330 | _aRecently the ATLAS Collaboration at CERN reported on the measurement of the branching ratio RΛb=Γ(Λ0b→ψ(2S)Λ0)/Γ(Λ0b→J/ψΛ0). The measured branching ratio RΛb=0.501±0.033(stat)±0.019(syst) was found to be lower than the covariant quark model prediction of RΛb=0.8±0.1 calculated by us recently. We present a detailed analysis of the branching ratio RΛb using a model-independent framework for the heavy-to-light form factors based on results from our previous papers. | ||
