Correlator webs of massive multiparton amplitudes at four loops: A study of boomerang webs
The logarithm of the soft function can be organised into sets of Feynman diagrams known as correlator webs(cwebs). We introduced a new formalism in Agarwal [] that allows one to determine several of the building blocks of cweb mixing matrices without explicit computations. In Agarwal [], we used this formalism …
