The Differential equation method: calculation of vertex-type diagrams with one non-zero mass

High Energy Physics - Phenomenology 2009-10-30 v1

Abstract

The differential equation method is applied to evaluate analytically two-loop vertex Feynman diagrams. Three on-shell infrared divergent planar two-loop diagrams with zero thresholds contributing to the processes Z --> bb bar (for zero b mass) and/or H --> gg are calculated in order to demonstrate a new application of this method.
