Diffraction and the Gluon Mass
M. B. Gay Ducati, F. Halzen, A. A. Natale
Abstract
We recently proposed a QCD-Pomeron described by the exchange of two non-perturbative gluons characterized by a dynamically generated gluon mass. It is here shown that data on elastic scattering, exclusive ρ production in deep inelastic scattering and the J/Ψ-nucleon total cross-section can be successfully described in terms of a single gluon mass mg0.37~GeV. We observe that the total cross sections of hadrons with small radii, such as J/Ψ, have a marked dependence on the effective gluon mass.
