AB - 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 --> b (b) over bar (for zero b mass) and/or H --> gg are calculated in order to demonstrate a new application of this method.
