摘要: This paper uses the background field method to calculate one-loop divergent corrections to the gauge field propagators in noncommutative U(1) gauge theory with scalar fields. It shows that for a massless scalar field, the gauge field propagators are renormalizable to θ2-order, but for a massive scalar field they are renormalizable only to θ-order.

Abstract: This paper uses the background field method to calculate one-loop divergent corrections to the gauge field propagators in noncommutative U(1) gauge theory with scalar fields. It shows that for a massless scalar field, the gauge field propagators are renormalizable to $\theta^2$-order, but for a massive scalar field they are renormalizable only to $\theta$-order.

Key words: noncommutative geometry, quantum field theory, renormalization
