Abstract.

We extend the Golec-Biernat-Wüsthoff model for virtual photon-proton scattering to include the resolved photon component explicitly. The parameters of the resolved photon component are taken from the literature, while the parameters of the dipole-nucleon interaction are fitted to the HERA data in a selected limited range of x and Q 2. A good agreement with the experimental data is obtained beyond the region of the fit.
