Gauge (in)dependence and UV/IR mixing

The gauge independence in connection with the UV/IR-mixing is discussed with the help of the non-commutative U(1)-gauge field model proposed by A. A. Slavnov with two different gauges: the covariant gauge fixing defined via a gauge parameter αand the non-standard axial-gauge depending on a fixed gauge direction n^μ.

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

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.
