A generating functional for infrared-safe QED amplitudes
Martin Ammon, Konrad Brandts, Federico Capone +1
We construct a generating functional for infrared-finite scattering amplitudes in massive quantum electrodynamics (QED) by including Faddeev-Kulish dressings in a holomorphic coher…

Conformal Blocks in Two and Four Dimensions from Oscillator Representations
Martin Ammon, Jakob Hollweck, Tobias Hössel +1
The explicit computation of higher-point conformal blocks in any dimension is usually a challenging task. For two-dimensional conformal field theories in Euclidean signature, the o…
