Summary
A unified approach to exclusive diffractive lepton- and hadron- induced processes based on a unique pomeron containing two terms,
a "soft" and a "hard" one, is suggested. The relative weight of the two terms is controlled by relevant \tilde Q^2=Q^2+M_V^2-dependent factors,
where Q^2 is the virtuality of the external photon (or proton, Q_p^2=m_p^2) and M is the mass of the produced vector meson.
The t dependence of the residue is controlled by the slopes (inverse radii) of the colliding particles, thus jus
