Abstract
Proc. of DIS 2012, 827-830; DESY
The production of $D^*$, $D^+$, $D^0$, $D_s$ and $\Lambda_c$ charm
hadrons in ep scattering at HERA was studied with the ZEUS detector,
and the fractions of c quarks hadronizing as a particular charm hadron
were derived. The measurement has been performed in the photoproduction
regime, using the full HERA II data set with a total integrated luminosity
of 372 $pb^{-1}$. The obtained fractions are compared to previous
results from HERA and from $e^+ e^-$ experiments.
