Bananas: multi-edge graphs and their Feynman integrals
Abstract
We consider multi-edge or banana graphs bn on n internal edges ei with different masses mi. We focus on the cut banana graphs (R(bn)) from which the full result R(bn) can be derived through dispersion. We give a recursive definition of (R(bn)) through iterated integrals. We discuss the structure of this iterated integral in detail. A discussion of accompanying differential equations, of monodromy and of a basis of master integrals is included.
