Feynman Diagrams and a Combination of the Integration by Parts ( IBP ) and the Integration by Fractional Expansion ( IBFE ) Techniques

Abstract

In this paper we show how to improve and extend the Integration by Fractional Expansion technique (IBFE) by applying it to certain families of scalar massive Feynman diagrams. The strategy is based on combining this method together with the Integration by Parts technique (IBP). In particular, we want to calculate certain Feynman diagrams which have a… (More)
