Induced Gauge Theory on a Noncommutative Space

High Energy Physics - Theory 2008-11-26 v3

Abstract

We consider a scalar ϕ4\phi^4 theory on canonically deformed Euclidean space in 4 dimensions with an additional oscillator potential. This model is known to be renormalisable. An exterior gauge field is coupled in a gauge invariant manner to the scalar field. We extract the dynamics for the gauge field from the divergent terms of the 1-loop effective action using a matrix basis and propose an action for the noncommutative gauge theory, which is a candidate for a renormalisable model.
