LUNA, E. G. S.. Diffraction and an infrared finite gluon propagator. Braz. J. Phys. [online]. 2007, vol.37, n.1a, pp.84-87. ISSN 0103-9733.

We discuss some phenomenological applications of an infrared finite gluon propagator characterized by a dynamically generated gluon mass. In particular we compute the effect of the dynamical gluon mass on pp and ${\bar{p}}p$ diffractive scattering. We also show how the data on gp photoproduction and hadronic gg reactions can be derived from the pp and ${\bar{p}}p$ forward scattering amplitudes by assuming vector meson dominance and the additive quark model.

Keywords : Diffractive dissociation; Dynamical gluon mass; Photoproduction.
