WebbFor some time now I have been wondering if you could not derive any sort of equations of motion from the Standard Model: L = − 1 4 F μ ν F μ ν + i ψ ¯ D ψ + ψ ¯ ϕ ψ + h. c. + D ϕ 2 − V ( ϕ). Since it is a Lagrangian shouldn't we be able to use the Euler-Lagrange equation to find some equations of motion?
