A FRESH LOOK AT THE (NON-) ABELIAN LANDAU-KHALATNIKOV-FRADKIN TRANSFORMATIONS

© 2018 Jagellonian University. All rights reserved. The Landau-Khalatnikov-Fradkin transformations (LKFTs) allow to interpolate n-point functions between different gauges. In this work, we offer a derivation for both Abelian and non-Abelian LKFT using gaugeinvariant fields. Secondly, this subject is studied using a direct path integral formalism, finding full consistency.
