Query: J/psi and psi(2S) Production and Polarization at the Tevatron   The NRQCD factorization approach for quarkonium production at hadron
colliders is reviewed. The prediction of J/psi and psi(2S) transverse
polarization at large transverse momentum is confronted with recent
experimental data, and potential shortcomings of the theoretical analysis are
discussed.
