Ward identity in noncommutative QED
arXiv:hep-ph/0211416 · doi:10.1142/S0217751X03015945
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 $γγ\to γγ$ scattering in noncommutative QED.
