All-multiplicity one-loop amplitudes in Born-Infeld electrodynamics from generalized unitarity
All-multiplicity one-loop amplitudes in Born-Infeld electrodynamics from generalized unitarity
A bstract We initiate a study of non-supersymmetric Born-Infeld electrodynamics in 4d at the quantum level. Explicit all-multiplicity expressions are calculated for the purely rational one-loop amplitudes in the self-dual (+ + … +) and next-to-self-dual ( − + … +) helicity sectors. Using a supersymmetric decomposition, d -dimensional unitarity …
