Gauge Independence of IR singularities in Non-Commutative QFT - and Interpolating Gauges

Abstract

IR divergences of a non-commutative U(1) Maxwell theory are discussed at the one-loop level using an interpolating gauge to show that quadratic IR divergences are independent not only from a covariant gauge fixing but also independent from an axial gauge fixing.
