Abstract:
The resolution of Dyson-Schwinger equations leads to the freezing of the QCD running coupling (effective charge) in the infrared, which is best understood as a dynamical generation of a gluon mass function, giving rise to a momentum dependence which is free from infrared divergences. We calculate the static interquark potential by assuming that it is given by a massive One Gluon Exchange Potential and compare it with phenomenological fits inspired by lattice QCD. We discuss possible physical interpretations of our results regarding heavy quarkonia spectroscopy. Reference: P.Gonzalez, V. Mathieu and V. Vento, PRD84, 114008 (2011).
