Description
The production of D*, D+, D0, Ds and Lambda_c charm hadrons and
their antiparticles in ep scattering at HERA was studied with
the ZEUS detector using the full HERA II data set.
The measurement has been performed in the photoproduction regime.
The fractions of c quarks hadronising as a particular charm hadron,
f(c -> D, Lambda_c), were derived in the visible kinematic range.
