An introduction to charmonium production and polarization at hadron colliders

Abstract: I will review the recent progress on J/Ψ polarization puzzle,
especially the impact of ηchadroproduction data on charmonium production and polarization.
As an interesting application, J/Ψsuppression serves as a signal for the existence of quark-gluon plasma.
Color-glass-condensate associated with the nonrelativistic QCD provide a comprehensive description of
J/Ψproduction in both pp and pA collisions.
