Study of the photon's pole structure in the noncommutative Schwinger model
Abstract
The photon self-energy of the noncommutative Schwinger model at two- and three-loop order is analyzed. It is shown that the mass spectrum of the model does not receive any correction from noncommutativity parameter (θ) at these orders. Also it remains unchanged to all orders. The exact one-loop effective action for the photon is also calculated.
