Article overview

Gauge dependence of the infrared behaviour of massless QED_3
Indrajit Mitra ; Raghunath Ratabole ; H. S. Sharatchandra ;
Date:	6 Oct 2005
Abstract:	Using the Zumino identities it is shown that in a class of non-local gauges, massless QED_3 has an infrared behaviour of a conformal field theory with a continuously varying anomalous dimension of the fermion. In the usual Lorentz gauge, the fermion propagator falls off exponentially for a large separation, but this does not correspond to a breaking of chiral symmetry.
