Masses and electric charges: gauge anomalies and anomalous thresholds
Cesar Gomez, Raoul Letschka
We work out in the forward limit and up to order in perturbation theory the collinear divergences. In this kinematical regime we discover new collinear divergences that we ar…
The Scales of the Infrared
Cesar Gomez, Raoul Letschka, Sebastian Zell
In theories with long-range forces like QED or perturbative gravity, loop corrections lead to vanishing amplitudes. There are two well-known procedures to address these infrared di…
Infrared Divergences and Quantum Coherence
Cesar Gomez, Raoul Letschka, Sebastian Zell
In theories with long-range forces like QED or perturbative gravity, only rates that include emitted soft radiation are non-vanishing. Independently of detector resolution, finite…
Damping self-forces and Asymptotic Symmetries
Cesar Gomez, Raoul Letschka
Energy conservation in radiating processes requires, at the classical level, to take into account damping forces on the sources. These forces can be represented in terms of asympto…
Memory and the Infrared
Cesar Gomez, Raoul Letschka
Memory effects in scattering processes are described in terms of the asymptotic retarded fields. These fields are completely determined by the scattering data and the zero mode par…
