Homological Finiteness Properties of Groupsg relations among the various Dirac matrices and we present the basics of calculating spinor traces. The tools given here can be used to further calculate lengthy and more complicated traces involving Dirac matrices. The transformation of spinors under Lorentz transformations is also presented consi

The Borel Construction and Bass-Serre Theorylculations are made as explicit as possible, in order to clarify many of the confusions that may arise when treating this topic. We will restrict our attention to the most academic example, which is (in my opinion) the QED Lagrangian. We shall use the dimensional regularization approach in . dimensi

Homological Finiteness Properties of Groups extensively treated. One example of IR-pole cancellation is presented. The two and three-body phase space integrals in . dimensions, needed for the calculation of IR divergent cross sections are also given.

Here we will present an example of how to reduce the number of calculated diagrams for a given process (which in this case will be a Higgs-like scalar decay to two photons through a charged scalar loop) using gauge
