  Many known models, which generally use a factorization hypothesis, give a
poor account of the decays B into J/psi + K(*). Usually there is a free overall
factor, which is fit to the data, so that tests of the models rely upon ratios.
The models tend to give too much K* compared to K and too much transverse
polarization compared to longitudinal. Our microscopic calculations, which use
perturbative QCD, do well for both ratios. A microscopic calculation allows us
to see how well factorization, heavy quark symmetry, and other features of
various models are working. In the present case, agreement with the
experimental ratios is dependent upon a breakdown of factorization for one of
the amplitudes.
