Tracking discontinuities in parameter space
Ruth Britto, Holmfridur S. Hannesdottir
We develop a geometric framework in Feynman-parameter space to determine constraints on the sequential discontinuities of Feynman integrals. Our method is based on tracking the def…
Cutting-Edge Tools for Cutting Edges
Ruth Britto, Claude Duhr, Holmfridur S. Hannesdottir +1
We review different notions of cuts appearing throughout the literature on scattering amplitudes. Despite similar names, such as unitarity cuts or generalized cuts, they often repr…
Generalized hypergeometric functions and intersection theory for Feynman integrals
Samuel Abreu, Ruth Britto, Claude Duhr +2
Feynman integrals that have been evaluated in dimensional regularization can be written in terms of generalized hypergeometric functions. It is well known that properties of these…
