====== TTP99-23 Combined analysis of diffractive and inclusive structure functions in the semiclassical framework ====== Small-$x$ DIS is described as the scattering of a partonic fluctuation of the photon off a superposition of target color fields. Diffraction occurs if the emerging partonic state is in a color singlet. Introducing a specific model for the averaging over all relevant color field configurations, both diffractive and inclusive parton distributions at some low scale $Q_0^2$ can be calculated. A conventional DGLAP analysis results in a good description of diffractive and inclusive structure functions at higher values of $Q^2$. |**W. Buchmueller, T. Gehrmann, A.
