We present predictions for the polar angle distribution at moderate values of p_t \\sim 4 - 20 GeV, covered by the Tevatron Run I data. We update the fits of NRQCD matrix elements and discuss their theoretical uncertainties. With our best fit values, no transverse polarization is expected at p_t \\sim 5 GeV, but the angular distribution is","authors_text":"M. Beneke (CERN), M.
