Abstract

Measurements of Charmonium production at the electron proton collider HERA are presented. In inelastic production the charmonium is formed from pairs that are produced in photon gluon fusion. The measurements of the cross sections and helicity distributions are compared to calculations performed in the framework of non-relativistic quantum chromodynamics (NRQCD), which includes both color-singlet and color-octet contributions.
