WebIn theoretical physics, a Fierz identity is an identity that allows one to rewrite bilinears of the product of two spinors as a linear combination of products of the bilinears of the individual spinors. It is named after Swiss physicist Markus Fierz.The Fierz identities are also sometimes called the Fierz–Pauli–Kofink identities, as Pauli and Kofink described a … WebOct 19, 2016 · 1. Consider the following quadri-linear. e ( 1234) = [ ψ ¯ 1 σ μ ν ψ 2] [ ψ ¯ 3 σ μ ν γ 5 ψ 4] Where ψ 's are spinors. I came across the identity: e ( 1234) = e ( 3412). I …
Web2. 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.
