Gauge-invariant dressed fermion propagator in massless QED_3
Indrajit Mitra, Raghunath Ratabole, H. S. Sharatchandra
The infrared behaviour of the gauge-invariant dressed fermion propagator in massless QED_3 is discussed for three choices of dressing. It is found that only the propagator with the…

Gauge dependence of the infrared behaviour of massless QED_3
Indrajit Mitra, Raghunath Ratabole, H. S. Sharatchandra
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 anomal…
