Description
Studies of heavy quarkonia production in the hadronic collisions are a very good tool for testing various aspects of QCD. Despite many theoretical attempts, the long-standing problem of J/psi's polarization has resisted solution. We present our recent study on the J/psi polarization observables \lambda's in a Color Glass Condensate (CGC) + Nonrelativistic QCQ (NRQCD) approach. Comparisons with LHCb and ALICE data on J/\Psi are shown that indicate quite good agreement with the data -- further test of this approach in high multiplicity proton-proton and proton-nucleus collisions are discussed.
