Field theories with p-form gauge potentials can possess "hidden" symmetries leaving the field strengths invariant on-shell without being gauge symmetries on-shell. The relevance of such symmetries to supersymmetric models is discussed. They provide central charges of supersymmetry algebras, play a particular rôle in duality relations, and lead to peculiar interactions. A multiplet of N=2 supersymmetry in four dimensions with two hidden central charges is presented.

“…At last we remark that in the case of local supersymmetry central charges necessarily have to be gauged, so our efforts may be viewed as preparatory steps toward a coupling of the VT multiplet to supergravity. For the linear and old nonlinear VT multipet couplings to superconformal gravity have already been constructed in [10], where again it was necessary to include a vector multiplet that provides the gauge field for local central charge transformations. Upon reduction to Poincaré supergravity this gauge field is identified with the graviphoton.…”

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.In their study of four-dimensional N = 2 supersymmetric vacua of heterotic string theory de Wit et al. [1] found that the dilaton and the antisymmetric tensor reside in an N = 2 vector-tensor multiplet. Although on-shell a vector-tensor (VT) multiplet is dual to an abelian vector multiplet, string theory may prefer the off-shell realization of the former. This is why possible interactions of the VT multiplet have been extensively studied in the last years. Among these, which include a variety of couplings to additional vector multiplets [2]-[9] and supergravity couplings [10], there are self-interactions. A self-interacting VT multiplet with nonlinear supersymmetry transformations had been constructed for the first time by Claus et al. in [2]. Only recently was it realized that there exists a second self-interacting version of the multiplet: in [11] we obtained what we shall call the new nonlinear vector-tensor (NLVT) multiplet in the following by gauging its central charge transformations. Promoting the global bosonic symmetry associated with the central charge of the VT multiplet to a local symmetry requires the presence of a vector potential, which in previous works was taken to sit in an additional abelian vector multiplet [2,3,8,9]. In [11] on the other hand it was shown that the VT multiplet's own vector field can serve as the necessary gauge connection, as well. The resulting new NLVT multiplet features nonpolynomial but local interactions. They were constructed by means of the Noether method as a deformation of the free action and its symmetries, with the supersymmetry algebra being realized only on-shell. In the present paper we derive an off-shell formulation of the new NLVT multiplet from a suitable set of constraints on the field strengths appearing in the N = 2 supersymmetry algebra with a gauged central charge. The Bianchi identities imply that as a consequence of these constraints all field strengths can be expressed in terms of a single real scalar 1

We will have to take this point into account in the next subsection when dualizing the Noether current into a 2-form.…”

We extend the system of ungauged N = 2, d = 4 supergravity coupled to vector multiplets and hypermultiplets with 2-form potentials. The maximal number of 2-form potentials that one may introduce is equal to the number of isometries of either the special Kähler or quaternionic Kähler sigma model. We show that the local supersymmetry algebra can be realized on the 2-form potentials. These 2-forms couple electrically to strings which we refer to as stringy cosmic strings. The 1/2 BPS bosonic world-sheet actions for these strings are constructed and we discuss the properties of the 1/2 BPS stringy cosmic string solutions.
