# Gauge dependence of Green’s functions in QCD and QED

@article{Nishijima2007GaugeDO, title={Gauge dependence of Green’s functions in QCD and QED}, author={Kazuhiko Nishijima and Anca Tureanu}, journal={The European Physical Journal C}, year={2007}, volume={53}, pages={649-657} }

When all Green’s functions are known in a given gauge we may raise the question of whether it is possible or not to derive the corresponding ones in a different gauge. The answer is negative in QCD but affirmative in QED provided that we confine ourselves to the covariant gauge characterized by a gauge parameter α. We shall discuss the physical significance of this conclusion.
