Fe b 20 05 Gauge ( in ) dependence and UV / IR mixing

Abstract

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 [5] with two different gauges: the covariant gauge fixing defined via a gauge parameter α and the non-standard axial-gauge depending on a fixed gauge direction n. mattems@hep.itp.tuwien.ac.at blaschke… (More)
