Abstract

Recently the ATLAS Collaboration at CERN reported on the measurement of the branching ratio R-Lambda b = Gamma(Lambda(0)(b) -> psi(2S)Lambda(0))/Gamma(Lambda(0)(b) -> J/psi Lambda(0)). The measured branching ratio R-Lambda b = 0.501 +/- 0.033(stat) +/- 0.019(syst) was found to be lower than the covariant quark model prediction of R-Lambda b = 0.8 +/- 0.1 calculated by us recently. We present a detailed analysis of the branching ratio R-Lambda b using a model-independent framework for the heavy-to-light form factors based on results from our previous papers.
