Ward identity in noncommutative QED

Abstract

Although noncommutative QED presents a nonabelian structure, it does not present structure constants. In view of this we investigate how Ward identity is satisfied in pair annihilation process and $\gamma \gamma \to \gamma \gamma$ scattering in noncommutative QED.
