The normalization calculation

Stage 5: the free massless scalar and the field-list issue › The normalization calculation · lines 1459–1474

Independently supply the four-dimensional free massless scalar on Minkowski space, its vacuum Wick fields, and their invariant polynomial domain. Let

Q =: ϕ^{2} :, K =: \partial_{ρ} ϕ \partial^{ρ} ϕ :,

T_{μν} =: \partial_{μ} ϕ \partial_{ν} ϕ : - \frac{1}{2} η_{μν} K .

The free equation is $□ ϕ = 0$ .
