A Solution to Coupled Dyson-Schwinger Equations for Gluons and Ghosts in Landau Gauge
Andreas Hauck, Reinhard Alkofer, Lorenz von Smekal
A truncation scheme for the Dyson-Schwinger equations of QCD in Landau gauge is presented which implements the Slavnov-Taylor identities for the 3-point vertex functions. Neglectin…

The Strong Running Coupling from an Approximate Gluon Dyson-Schwinger Equation
R. Alkofer, A. Hauck, L. von Smekal
Using Mandelstam's approximation to the gluon Dyson-Schwinger equation we calculate the gluon self-energy in a renormalisation group invariant fashion. We obtain a non-perturbative…
