Color Evaporation Description of Inelastic Photo-Production of J/\psi at   HERA
  The H1 Collaboration recently reported a new analysis on the inelastic photo- production of J/\psi mesons at DESY HERA ep collider. We show that these new experimental results are well described by the Color Evaporation Model for quarkonium production. Moreover, this new data requires the introduction of resolved photon contributions in order to explain the results on small charmonium energy fraction, indicating that colored c \bar{c} pairs also contribute to the process.
