Noncommutative Sugawara Construction

The noncommutative extension of the Sugawara construction for free massless fermionic fields in two dimensions is studied. We prove that the equivalence of the noncommutative Sugawara energy-momentum tensor and symmetric energy-momentum tensor persists in the noncommutative extension. Some relevant physical results of this equivalence are also discussed.

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 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.
