Dependence of the Chiral Symmetry Restoration Transition on the Quark Self-Energy Kernel
A. Bender, W. Detmold, A. W. Thomas
The dependence of the dressed quark propagator on the quark chemical potential is investigated in various models based on the Dyson-Schwinger equations. We find that the critical c…

Analytic Structure of the Quark Propagator in a Model with an infrared vanishing Gluon Propagator
Axel Bender, Reinhard Alkofer
The Dyson-Schwinger equation for the quark self energy is solved in rainbow approximation using an infrared (IR) vanishing gluon propagator that introduces an IR mass scale . Th…

Pion Loop Contribution to the Electromagnetic Pion Charge Radius
Reinhard Alkofer, Axel Bender, Craig D. Roberts
A phenomenological Dyson-Schwinger equation approach to QCD, formalised in terms of a QCD based model field theory, is used to calculate the electromagnetic charge radius of the pi…
