New N=4 Superfields and Sigma-models

TL;DR

This paper introduces new N=4 superfield representations in two dimensions that avoid traditional multiplets, potentially enabling novel superspace formulations of WZWN models beyond existing no-go theorems.

Contribution

It presents novel N=4 superfield representations that do not rely on chiral or twisted chiral multiplets, opening new avenues for superspace formulations.

Findings

New superfield representations constructed for D=2, N=4 supersymmetry.

Potential to bypass no-go theorems in superspace formulations.

Implications for WZWN-models and supersymmetric theories.

Abstract

In this note, we construct new representations of D=2, N=4 supersymmetry which do not involve chiral or twisted chiral multiplets. These multiplets may make it possible to circumvent no-go theorems about N=4 superspace formulations of WZWN-models.
