Factorized soft graviton theorems at loop level
Johannes Broedel, Marius de Leeuw, Jan Plefka +1
We analyze the low-energy behavior of scattering amplitudes involving gravitons at loop level in four dimensions. The single-graviton soft limit is controlled by soft operators whi…
Constraining subleading soft gluon and graviton theorems
Johannes Broedel, Marius de Leeuw, Jan Plefka +1
We show that the form of the recently proposed subleading soft graviton and gluon theorems in any dimension are severely constrained by elementary arguments based on Poincaré and g…
Deformed one-loop amplitudes in N = 4 super-Yang-Mills theory
Johannes Broedel, Marius de Leeuw, Matteo Rosso
We investigate Yangian-invariant deformations of one-loop amplitudes in N = 4 super-Yang-Mills theory employing an algebraic representation of amplitudes. In this language, we repr…
