Web2- Derive the \Gordon identity": u(p0) u(p) = u(p0) p0 + p 2m + i˙ q 2m u(p); where q= (p p0). 3- Problem 3.8 of Peskin and Schroeder (page 76). It will be useful to go through the table on page 71 that summarizes the transformation properties of the fermion bilinears under C and P. Focus on , which couples to the electromagnetic eld A . WebA convenient way to derive these relations is by converting the Clebsch–Gordan coefficients to Wigner 3-j symbols using 3. The symmetry properties of Wigner 3-j symbols are much simpler. ... This identity also holds if the sign of any j i is reversed, or if any of them are substituted with an m i instead. Relation to Wigner 3-j symbols

The action reads: S = ∫d4x√− g( − 1 2g μ ν ∇ μ ϕ∇ ν ϕ − 1 2m2ϕ2) For the kinetic term you have: where I've summed the terms with dummy indices. From Leibnitz rule we know that: ∇ μ (δϕ∇ μ ϕ) = ∇ μ (δϕ)∇ μ ϕ + δϕ∇ μ ∇ μ ϕ
