Radiative Correctionsin Noncommutative QED

TL;DR

This paper investigates one-loop radiative corrections in noncommutative QED, focusing on magnetic dipole moment modifications and IR divergence behavior, revealing similarities to standard QED.

Contribution

It provides the first detailed calculation of radiative corrections in noncommutative QED, including magnetic dipole moment shifts and IR divergence analysis.

Findings

Magnetic dipole moment receives corrections due to noncommutativity.

IR divergences cancel when combining Bremsstrahlung and vertex corrections.

Results parallel those in ordinary QED with noncommutative modifications.

Abstract

We study the radiative corrections of the noncommutative QED at the one-loop level. A correction of the magnetic dipole moment due to the noncommutativity are evaluated. As in the ordinary QED, IR divergence is shown to vanish when we combine both the tree level Bremsstrahlung diagram and the one-loop electron vertex function.
