Abstract: We show that the infrared behaviour of massless QED in space-time
dimensions 2 < d < 4 is given by a non-trivial conformal field theory (AmatiTesta model) with a non-canonical scale dimension one for the photon. Our
analysis is done to all orders in 1/N expansion in a specific non-local gauge. We
obtain the anomalous dimensions of gauge invariant composite operators.
