The Differential equation method: calculation of vertex-type diagrams with one non-zero mass
arXiv:hep-ph/9707492 · doi:10.1016/S0370-2693(97)01195-7
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.
