Abstract :
We give an off-shell formulation of the N=2 supersymmetric new nonlinear vector–tensor multiplet. Interactions arise in this model as a consequence of gauging the central charge of the supersymmetry algebra, which in contrast to previous models with local central charge is achieved without a coupling to a vector multiplet. Furthermore, we present a new action formula that follows from coupling the N=2 linear multiplet to the vector–tensor multiplet.
