Landau-Khalatnikov-Fradkin transformation and hatted zeta-values
A. V. Kotikov, S. Teber
We show an exact formula obtained in [1], which relates hatted and standard zeta-values to all orders of perturbation theory. The formula is based on the Landau-Khalatnikov-Fradkin…
Landau-Khalatnikov-Fradkin transformation of the fermion propagator in massless reduced QED
A. James, A. V. Kotikov, S. Teber
We study the gauge-covariance of the massless fermion propagator in reduced Quantum Electrodynamics (QED). Starting from its value in some gauge, we evaluate an all order expressio…
Landau-Khalatnikov-Fradkin transformation and the mystery of even -values in Euclidean massless correlators
A. V. Kotikov, S. Teber
The Landau-Khalatnikov-Fradkin (LKF) transformation is a powerful and elegant transformation allowing to study the gauge dependence of the propagator of charged particles interacti…
Addendum to "Critical behaviour of ()-dimensional QED: -corrections in an arbitrary non-local gauge"
A. V. Kotikov, S. Teber
Dynamical chiral symmetry breaking (DSB) is studied within ()-dimensional QED with four-component fermions. The leading and next-to-leading orders of the expansion…
