Fierz transformations Fierz identities are often useful in quantum field theory calculations. They are connected to reordering of field operators in a contact four-particle interaction. The basic task is: given four complex fields ψ1,2,3,4, which carry a (spacetime or internal) index, let us consider an interaction (ψ1 Aψ2)(ψ3 Bψ4). (1)

If at tree-level Fierz transformations are required but the corresponding shifts vanish, then the corresponding blocks in R̂(0) and R̂(1) are still the same. 3. In certain blocks the necessity of performing Fierz transformation would introduce the shifts which will introduce EV operators and hence contribute to the R̂(1). 1. uk healthcare professional coding jacket saleWebSelect 2 - Towards a quantum field theory. 2 - Towards a quantum field theory pp 41-103.
