Seiberg-Witten Maps to All Orders for Scattering Processes in NCQED — •Jörg Zeiner, Thorsten Ohl, and Reinhold Rückl — Institut für Theoretische Physik und Astrophysik, Universität Würzburg

We construct the Seiberg-Witten maps for noncommutative QED to all orders of the noncommutative parameter θ_µν, but to finite order in the gauge field A_µ. Furthermore, we calculate the scattering amplitude for e⁺e⁻→γγ for energies above the noncommutative scale and study the tree-level unitarity of the theory.
