Lectures On Qed And Qcd: Practical Calculation And Renormalization Of One- And Multi-loop Feynman Diagrams

The increasing precision of experimental data in many areas of elementary particle physics requires an equally precise theoretical description. In particular, radiative corrections (described by one- and multi-loop Feynman diagrams) have to be considered. Although a growing number of physicists are involved in such projects, multi-loop calculation methods can only be studied from original publicat...
