The gluon mass leads to an infrared finite coupling constant.
Implications for phenomenological approaches like Dynamical Perturbation Theory.
Abstract
We briefly discuss some results obtained recently about dynamical gluon mass generation. We comment that this mass provides a natural QCD infrared cutoff and also implies an infrared finite coupling constant. We also discuss the phenomenological applications of these results and how they can be treated in the context of the so-called Dynamical Perturbation Theory.
