We investigate coherence-length effects and hadron attenuation in lepton scattering off nuclei in the kinematic regime of the HERMES experiment. The elementary electron-nucleon interaction is described within the event generator PYTHIA, while a full coupled-channel treatment of the final-state interactions is included by means of a BUU transport model. The results of our calculations are in good agreement with the experimentally measured transparency ratio of incoherent r0 electroproduction off 14N and the multiplicity ratio RMh for charged hadrons, pions, kaons, protons and anti-protons in deep inelastic scattering off 14N and 84Kr targets.
