Abstract
We present an N=2 multiplet including a three-index antisymmetric
tensor gauge potential, and describe it as a solution to the Bianchi
identities for the associated fieldstrength superform, subject to some
covariant constraints, in extended central charge superspace.
We find that this solution is given in terms of an 8+8 tensor multiplet
subject to an additional constraint.
We give the transformation laws for the multiplet as well as invariant
superfield and component field lagrangians, and mention possible couplings
to other multiplets.
We also allude to the relevance of the 3-form
geometry for generic invariant supergravity actions.
