Inelastic J/Psi photoproduction at HERA

Inelastic $J/\psi$ photoproduction is an interesting area where one can test QCD predictions. This article reviews the recent experimental results obtained by the ZEUS and H1 Collaborations. %The H1 results correspond to an integrated luminosity of approximately %166 pb$^{-1}$, taken in the years 2006-2007. Single differential and double differential cross sections have been measured by the H1 Collaboration using an integrated luminosity of 166 pb$^{-1}$, taken in the years 2006-2007. The $J/\psi$ decay angular distributions have been measured in inelastic photoproduction by the ZEUS Collaboration, with an integrated luminosity of 468 pb$^{-1}$. These results have an increased precision compared to previous analyses. The measurements are compared to various theoretical predictions at leading and next-to-leading order in QCD.
