Abstract

New results from the H1 and ZEUS experiments on photoproduction of open charm at HERA are presented. Final states containing charm events are identified by the reconstruction of charmed hadrons. These data are used to extract information on charm fragmentation ratios and fractions, to test QCD predictions on inclusive D ^*± meson production and to investigate di-jet angular distributions in photoproduction of charm.
