Using FeynArts and FormCalc: Slides ⋅ Examples - I'm the contact person for physics in the steering group of the
Fachgruppe Computeralgebra.

Twice a year Fachgruppe issues the Computeralgebra-Rundbrief which contains news and information related to computer algebra, such as new systems, applications, conference announcements, surveys of publications, etc.

Am I content? — No, and I hope I never will be.
