Charm-hadron production at hadron colliders

Recent results on charm hadron production are presented, using data recorded in proton-proton collisions at the Large Hadron Collider and in proton-antiproton collisions at the Tevatron. These results include the production of charmonium and of open charm mesons, and their comparison with theoretical predictions. Measurements of the associated production of hidden or open charm mesons with additional quarkonium states are also presented.
