Summary, in English

Monte Carlo models of DIS e-gamma scattering must describe hard emissions as well as the soft and collinear limits. Comparison with the observed experimental hadronic energy flow has shown that various models underestimate the high-p_T contribution, in particular at low-x. We have attempted to tune the Herwig, Pythia and Ariadne models to improve the agreement with the data, and to understand the physical implications of the changes required. Unless the physics of these processes is understood it will not be possible to unfold the photon structure functions F_2^\gamma from the e^+e^- data without large model dependent systematic errors.
