On non-linear superfield versions of the vector-tensor multiplet

Abstract

We propose a harmonic superspace description of the non-linear vector-tensor N=2 multiplet. We show that there exist two inequivalent version: the old one in which one of the vectors is the field-strength of a gauge two-form, and a new one in which this vector satisfies a non-linear constraint and cannot be expressed in terms of a potential. In this the new version resembles the non-linear N=2 multiplet. We perform the dualization of both non-linear versions and discuss the resulting Kähler potentials. Finally, we couple the non-linear vector-tensor multiplet to an abelian background gauge multiplet.
