TL;DR

This paper develops superfield constraints for a linear vector-tensor multiplet with a gauged central charge, revealing nonpolynomial behavior in the gauge field for transformations and actions.

Contribution

It introduces a consistent superfield framework for the vector-tensor multiplet with gauged central charge, including nonpolynomial gauge field interactions.

Findings

Superfield constraints for the multiplet are derived.

Central charge transformations are nonpolynomial in the gauge field.

The action exhibits nonpolynomial dependence on the gauge field.

Abstract

We derive consistent superfield constraints for the linear vector-tensor multiplet with gauged central charge. The central charge transformations and the action turn out to be nonpolynomial in the gauge field.
