The Effective Potential in the Massive $ϕ_4^4$ Model

By applying the renormalization group equation, it has been shown that the effective potential $V$ in the massless $ϕ_4^4$ model and in massless scalar quantum electrodynamics is independent of the scalar field. This analysis is extended here to the massive $ϕ_4^4$ model, showing that the effective potential is independent of $ϕ$ here as well.
