MODE DEPENDENT FIELD RENORMALIZATION AND TRIVIALITY

R. Tarrach

Open publisher page 1 citations

Abstract

We critically analyze the introduction of an independent zero momentum mode field renormalization for Phi4. It leads to an infrared divergent effective action. It does not achieve its purpose: triviality still gives massless particles in the broken phase in the continuum limit. It leads to an effective potential which is not the low energy limit of the effective action.
