We calculate the partonic cross sections for the hadroproduction of polarized χcJ mesons using the factorization formalism of nonrelativistic QCD. We also describe how the polarization is passed on to the J/ψ mesons in the radiative feed-down χcJ→J/ψ+γ and in the double-cascade decays of ψ′ mesons via χcJ intermediate states. These represent the missing ingredients needed to predict the polarization of prompt J/ψ mesons at the Fermilab Tevatron.
