Abstract
Using the color evaporation model (CEM), we consider the decay rate of B → J/ψ + X and the polarization of J/ψ therein, and we compare the results with the data and with the predictions by the nonrelativistic quantum chromodynamics (NRQCD) approach. In the GEM, we use the input parameter determined from photo/hadro productions of J/ψ, and we find that it is difficult to make the CEM predictions confront with the CLEO data on these observables.
