Modular application of an Integration by Fractional Expansion (IBFE) method to multiloop Feynman diagrams II
A modular application of the integration by fractional expansion method for evaluating Feynman diagrams is extended to diagrams that contain loop triangle subdiagrams in their geometry. The technique is based in the replacement of this module or subdiagram by its corresponding multiregion expansion (MRE), which in turn is obtained from Schwinger’s parametric representation of the diagram. The r...
متن کاملModular application of an Integration by Fractional Expansion (IBFE) method to multiloop Feynman diagrams
We present an alternative technique for evaluating multiloop Feynman diagrams, using the integration by fractional expansion method. Here we consider generic diagrams that contain propagators with radiative corrections which topologically correspond to recursive constructions of bubble type diagrams. The main idea is to reduce these subgraphs, replacing them by their equivalent multiregion expa...
متن کاملAutomatic Feynman diagram calculation with xloops –a short overview
xloops is a program package that calculates Feynman diagrams by using computer algebra systems. In this paper it is shown which problems to be solved by computer algebra arise during such calculations, and how this problems are handled in the framework of xloops.

We apply negative dimensional integration method (NDIM) to three outstanding gauges: Feynman, light-cone and Coulomb gauges. Our aim is to show that NDIM is a very suitable technique to deal with loop integrals, being them originated from any gauge choice. In Feynman gauge we perform scalar two-loop four-point massless integrals; in the light-cone gauge we calculate scalar two-loop integrals co...
متن کاملEvaluating multiloop Feynman integrals by differential equations
One year ago Henn suggested a new approach to solve differential equations for multiloop Feyn-man integrals. It is based on the notion of uniform transcendentality. A brief review of applications of this approach is presented.
