Does the ``Soft Pomeron'' Cope with the HERA Data?
Abstract
Description
It is demonstrated that the "soft pomeron" (together with a secondary reggeon) describing cross-sections of hadron-hadron collisions is fairly able to describe the energy dependence of cross-sections of exclusive (virtual) photoproduction of vector mesons $(ρ^0, ϕ, J/ψ)$ obtained at HERA. However these poles are insufficient for description of the total DIS cross-section.
