The N=2 Vector-tensor Multiplet, Central Charge Superspace, and Chern-simons Couplings
We present a new, alternative interpretation of the vector-tensor multiplet as a 2-form in central charge superspace. This approach provides a geometric description of the (non-trivial) central charge transformations ab initio and is naturally generalized to include couplings of Chern-Simons forms to the antisymmetric tensor gauge field, giving rise to a N = 2 supersymmetric version of the Gree...
متن کاملN=2 Central Charge Superspace and a Minimal Supergravity Multiplet
We extend the notion of central charge superspace to the case of local supersymmetry. Gauged central charge transformations are identified as diffeomorphisms at the same footing as space-time diffeomorphisms and local supersymmetry transformations. Given the general structure we then proceed to the description of a particular vector-tensor supergravity multiplet of 24 + 24 components, identifie...
متن کامل6 v 1 1 S ep 1 99 6 VECTOR - TENSOR MULTIPLET IN N = 2 SUPERSPACE WITH CENTRAL CHARGE
We use the four-dimensional N = 2 central charge superspace to give a geometrical construction of the Abelian vector-tensor multiplet consisting, under N = 1 supersymmetry, of one vector and one linear multiplet. We derive the component field supersymmetry and central charge transformations, and show that there is a super-Lagrangian, the higher components of which are all total derivatives, all...
متن کاملA Two-form Formulation of the Vector-tensor Multiplet in Central Charge Superspace
A two-form formulation for the N = 2 vector-tensor multiplet is constructed using superfield methods in central charge superspace. The N = 2 non-Abelian standard supergauge multiplet in central charge superspace is also discussed, as is with the associated Chern-Simons form. We give the constraints, solve the Bianchi identities and present the action for a theory of the vector-tensor multiplet ...
