Abstract
The differential equation method is applied to evaluate analytically t wo-loop vertex Feynman diagrams. Three on-shell infrared divergent pla nar two-loop diagrams with zero thresholds contributing to the process es Z --> b (b) over bar (for zero b mass) and/or H --> gg are calculat ed in order to demonstrate a new application of this method.
