Coleman–Weinberg potential
text:
The Coleman–Weinberg model represents quantum electrodynamics of a scalar field in four-dimensions. The Lagrangian for the model is where the scalar field is complex, F μ ν = ∂ μ A ν − ∂ ν A μ is the electromagnetic field tensor, and D μ = ∂ μ − i A μ the covariant derivative containing the electric charge e of the electromagnetic field. Assume that λ is nonnegative. Then if the mass term is tachyonic, m 2 < 0 there is a spontaneous breaking of the gauge symmetry at low energies, a variant of th
