TL;DR: In this article, a perturbative QCD analysis of nuclear shadowing in the deep inelastic scattering at smallx in terms of the spatial wave function of virtual photons is presented.

TL;DR: In this paper, scaling properties of the diffraction dissociation of virtual photons in a deep inelastic scattering were studied in perturbative QCD and the authors found that quarks carry ≈ 10% of pomeron's momentum.

TL;DR: In this paper, the color dipole phenomenology of diffractive photo-and electroproduction was developed for light vector mesons and their radial excitations, and a direct evaluation of the dipole cross section from these data was presented.

TL;DR: In this article, the authors discuss how the energy and Q2 dependence of elastic production of vector mesons at HERA will allow scanning the dipole cross-section as a function of dipole size r. They also present predictions for the effective intercept in the kinematic range of the forthcoming HERA experiments, which can shed much light on the nonperturbative component of the pomeron.

TL;DR: Experimental results from HERA on diffractive vector meson production and their theoretical interpretation within microscopic QCD are reviewed with an emphasis on the BFKL color dipole and k T -factorization approaches.
