Diffraction and the gluon mass
Copyright policy )Diffraction and the gluon mass
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 $m_g\simeq0.37$~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.
