Measurements of charmed hadrons production in deep inelastic scattering with ZEUS

The Hadron Electron Ring Accelerator, HERA, is a unique facility to study the scattering between electrons and protons at very high energies. Its two colliding experiments, ZEUS and H1, have been giving important contributions to the understanding of the subatomic world. After a brief overview of the HERA physics and of the ZEUS detector, the analysis of charm production in deep inelastic scattering measured with ZEUS will be presented. Charm has been tagged by reconstructing D^*±, D⁰, D^±, D_s^± and Λ_c^± charm hadrons and the charm fragmentation ratios and fractions are measured.
