Study of the photon’s pole structure in the noncommutative Schwinger model
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 the noncommutativity parameter ([Formula: see text] ) at these orders. Also it remains unchanged to all orders....
