A numerical test of differential equations for one- and two-loop sunrise diagrams using configuration space techniques

, 2012
We use configuration space methods to write down one-dimensional integral representations for one- and two-loop sunrise diagrams (also called Bessel moments) which we use to numerically check on the correctness of the second order differential equations ...

On the evaluation of a certain class of Feynman diagrams in x-space: Sunrise-type topologies at any loop order

, 2005
We review recently developed new powerful techniques to compute a class of Feynman diagrams at any loop order, known as sunrise-type diagrams. These sunrise-type topologies have many important applications in many different fields of physics and we ...
