Polarization of Prompt J/\psi and \Upsilon (nS)

Jungil Lee

We review predictions, based on the nonrelativistic QCD factorization framework, for the polarizations of prompt J/\psi 's and  \Upsilon (nS)'s produced at the Fermilab Tevatron. We also discuss the effect of relativistic corrections on the theoretical prediction for the polarization of prompt J/\psi 's at the Tevatron.
