Webfierz. Perform a Fierz transformation on a product of four spinors. Change the order of the spinors in a four-spinor expression using a Fierz transformation. This relies on the generic fact that Dirac gamma matrices satisfy the completeness relation. ∑ a ( Γ a) i j ( Γ a) k l = δ i l δ j k. The following example explains the typical usage ... 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.
