Unitarity Cuts of Integrals with Doubled Propagators

Article, Preprint English OPEN
Søgaard, Mads; Zhang, Yang;
(2014)

We extend the notion of generalized unitarity cuts to accommodate loop integrals with higher powers of propagators. Such integrals frequently arise in for example integration-by-parts identities, Schwinger parametrizations and Mellin-Barnes representations. The method i... View more
