Two-photon contributions to the Rosenbluth cross-section in the Skyrme model

Abstract

We study two-photon contributions to the elastic electron nucleon scattering within the Skyrme model. In particular we focus on the role of the anomaly that enters via the Wess-Zumino term and explain how this induces an axial current interaction.
