Abstract

Abstract Recent progress in the calculation of two-loop self-energy diagrams is reviewed. At first we point out the new graphic possibilities in our ‘Feynman diagram analyzer’ ( DIANA), which of course is not only applicable for self-energies. Further we mention an interesting development in the reduction of on-shell two-loop self-energy diagrams including their master integrals for one massive parameter. Finally an application of our methods to the two-loop photon self-energy in the Standard Model (SM) is described.
