Polarized J/psi from chicJ and psi' Decays at the Tevatron
Abstract
We calculate the partonic cross sections for the hadroproduction of polarized chicJ mesons using the factorization formalism of nonrelativistic QCD. We also describe how the polarization is passed on to the J/psi mesons in the radiative feed-down chicJ -> J/psi + gamma and in the double-cascade decays of psi' mesons via chicJ intermediate states. These represent the missing ingredients needed to predict the polarization of prompt J/psi mesons at the Fermilab Tevatron.
