Diffractive parton distributions and the saturation model

We construct diffractive parton distributions in the model of DIS diffraction in which the diffractive state is formed by the $q\bar{q}$ and $q\bar{q}g$ components. The interaction of such systems with the proton is described by the dipole cross section given by the saturation model. We find Regge factorization property with the measured at HERA depenedence on energy. The found parton distributions are evolved with the DGLAP evolution equations to make a comparison with the data.
