Landau–Khalatnikov–Fradkin Transformation and Hatted $\zeta$-Values
Résumé
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 (LKF) transformation between the massless propagators of charged particles interacting with gauge fields, in two different gauges.
