Residues on Permanent Pinches: Finite Integrals and Leading Divergences
Dimitri Corradini, Cristian Vergu, Shun-Qing Zhang
We study infrared (IR) divergences from the point of view of permanent pinches. We show how canceling permanent pinches allows us to form finite linear combinations of integrals. W…
The Colour Dependence of Amplitudes
Jacob L. Bourjaily, Michael Plesser, Cristian Vergu
We describe how to construct a spanning set of linearly-independent, automatically orthogonal colour tensors for scattering amplitudes involving coloured particles transforming und…
Landau Analysis in Momentum Space with Massless Particles: an Amuse Bouche
C. Vergu
We illustrate how methods from Landau analysis that have been developed for studying the properties of massive Feynman integrals in momentum space can be generalized to massless in…
The Many Colours of Amplitudes
Jacob L. Bourjaily, Michael Plesser, Cristian Vergu
We study the colour-dependence of scattering amplitudes in Yang-Mills theory with arbitrary (but fixed) gauge group and various representations of charged matter. When the rank of…
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…
Cutkosky representation and direct integration
C. Vergu
We present a new method of direct integration of Feynman integrals based on the Cutkosky representation of the integrals. In this representation we are able to explicitly compute t…
