The Landau Bootstrap
Holmfridur Hannesdottir, Andrew McLeod, Matthew D. Schwartz +1
We advocate a strategy of bootstrapping Feynman integrals from just knowledge of their singular behavior. This approach is complementary to other bootstrap programs, which exploit…

Minimal Cuts and Genealogical Constraints on Feynman Integrals
Holmfridur S. Hannesdottir, Luke Lippstreu, Andrew J. McLeod +1
We introduce an efficient method for deriving hierarchical constraints on the discontinuities of individual Feynman integrals. This method can be applied at any loop order and part…
