Instanton constraints and renormalization

High Energy Physics - Theory 2009-11-11 v1

Abstract

The renormalization is investigated of one-loop quantum fluctuations around a constrained instanton in ϕ4\phi ^4-theory with negative coupling. It is found that the constraint should be renormalized also. This indicates that in general only renormalizable constraints are permitted.
