Query: Quarkonia production and polarization at the hadron colliders   This talk presents a review of recent results for quarkonium production at
the LHC from ATLAS, CMS, LHCb, and ALICE. Production cross sections for
$J/\psi$, $\psi(2S)$, and $\Upsilon(mS)$, and production ratios for
$\chi_{c,bJ}$ are found to be in good agreement with predictions from
non-relativistic QCD. In contrast, spin-alignment (polarization) measurements
seem to disagree with all theoretical predictions. Some other production
channels useful for investigating quarkonium hadroproduction mechanisms are
also considered.
