DESCRIPTION:Speakers: Michel Sauter (ETH Zurich)\nRecent measurements of f
 inal states including charm hadrons observed\nat the HERA collider are pre
 sented. The H1 and ZEUS collaborations\ncombined their D* differential cro
 ss section measurements and reach\nprecisions as good as 5-10%\, whereas t
 he theory uncertainties are much\nlarger. Using the ZEUS experiment\, D* p
 roduction was measured at\ndifferent centre-of-mass energies. The producti
 on of D1 and D*2 mesons\nwere also measured. Charm fragmentation fractions
  were obtained for\nvarious charm hadrons and are found to be compatible w
 ith data\ncollected at e+e- colliders. Finally\, the production of inelast
 ic J/psi \nmesons in the hadronic final state is investigated.\n\nhttps://
