Leading Baryon Production at Hera

New results on leading baryon production at HERA are presented for cross sections in photoproduction, in deep inelastic scattering and in the range in between these two kinematic regions. They are interpreted in terms of a Regge parameterization and, for the data with medium to high photon virtuality, in terms of structure functions. Vertex factorization is tested for these leading baryon data, as well as for events with a dijet system or a ρ meson in the final state.
