SpletTrace Theorems We must now digress and establish useful properties of traces of products of Dirac matrices. These properties will allow us to calculate cross-sections without ever looking directly at a Dirac matrix or spinor. They are derived from the commutation algebra of the 's and are valid independently of the choice of representation … Splet24. apr. 2024 · It can sometimes be useful to write gamma matrices as where the latin indices contract with spinors and other gamma matrices, while greek indices contract with spacetime objects like derivatives or the metric. At least I find this useful when trying to keep everything straight. Traces are taken over spinor indices.
