TL;DR
This paper demonstrates that three-dimensional supersymmetric quantum electrodynamics (Susy QED) remains finite at all loop orders in a specific gauge, highlighting its ultraviolet stability.
Contribution
It proves the all-order perturbative finiteness of 3D Susy QED within the superfield formalism, a significant result for supersymmetric gauge theories.
Findings
Susy QED is finite at all loops in a particular gauge.
Ultraviolet divergences are absent in the studied formalism.
The superfield approach effectively reveals the theory's finiteness.
Abstract
Within the superfield formalism, we study the ultraviolet properties of the three-dimensional supersymmetric quantum electrodynamics. The theory is shown to be finite at all loops orders in a particular gauge.
