Diffraction and the Gluon Mass

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 $\rho$ production in deep inelastic scattering and the $J/\Psi$-nucleon total cross-section can be successfully described in terms of a single gluon mass $m_g\simeq 0.37$~GeV. We observe that the total cross sections of hadrons with small radii, such as $J/\Psi$, have a marked dependence on the effective gluon mass.
