Abstract

Two component model for a description of the electromagnetic nucleon structure functions in low-x region, based on generalized vector dominance and color dipole approaches is briefly described. The model operates with the mesons of ρ-family having the mass spectrum of the form m2n = m 2 ρ (1 + 2n) and takes into account the nondiagonal transitions in meson-nucleon scattering. The special cut-off factors are introduced in the model, to exclude the γ − qq− V transitions in the case of the narrow qq pairs. For the color dipole part of the model the well known FKS-parameterization is used.
