Discontinuity at the Pole
Dominik Haslehner, Elena Kaiser, Javi Serra +1
The exchange of a particle whose mass is taken to zero need not reproduce the exchange of a particle that is strictly massless from the outset. We derive a general on-shell diagnos…
Renormalising the Field-Space Geometry
Patrick Aigner, Luigi Bellafronte, Emanuele Gendy +2
We present a systematic study of one-loop quantum corrections in scalar effective field theories from a geometric viewpoint, emphasizing the role of field-space curvature and its r…
RG of GR from On-shell Amplitudes
Pietro Baratella, Dominik Haslehner, Maximilian Ruhdorfer +2
We study the renormalization group of generic effective field theories that include gravity. We follow the on-shell amplitude approach, which provides a simple and efficient method…
