Dual equivalence between the Maxwell-Chern-Simons theory and two self-dual massive models interacting with matter in $\mathcal{N}=2$, $d=3$ superspace

TL;DR

This paper demonstrates the dual equivalence in $ ext{N}=2$, $d=3$ superspace between the Maxwell-Chern-Simons theory and two self-dual massive models interacting with matter, using master actions and generating functionals.

Contribution

It extends the duality between Maxwell-Chern-Simons and self-dual models to include matter fields in $ ext{N}=2$, $d=3$ superspace, establishing the equivalence through master actions and functional analysis.

Findings

Duality holds in the presence of matter superfields.

Master actions interpolate between models, confirming equivalence.

Generating functionals demonstrate the duality explicitly.

Abstract

We investigate the $\mathcal{N} = 2$ supersymmetric generalization of the dual equivalence between the Maxwell-Chern-Simons model and two massive self-dual models. One of the self-dual models is described by a real scalar superfield, while the other is described by a chiral spinor superfield. The equivalence is analyzed in the presence of dynamical matter chiral superfields. Initially, we establish the duality by demonstrating the existence of master actions that interpolate between the models. We then show that the field equations are identical when the proper identifications are made. Finally, we confirm the dual equivalence by defining a master generating functional, which, after changing the variables, provides the generating functionals of the Maxwell-Chern-Simons model and the two massive self-dual models coupled to matter.
