چکیده
A concise geometrical formulation of N = 4 supergravity containing an antisymmetric tensor gauge field is given in central charge superspace: graviphotons are identified in the super–vielbein on the same footing as the vierbein and the Rarita–Schwinger fields. As a consequence of superspace soldering, Chern–Simons terms in the fieldstrength of the antisymmetric tensor arise as an intrinsic property of superspace with central charge coordinates.

F - 13288 Marseille – Cedex 9 N = 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 کاملEquations of motion for N = 4 supergravity with antisymmetric tensor from its geometric description in central charge superspace
We consider the geometrical formulation in central charge superspace of the N = 4 supergravity containing an antisymmetric tensor gauge field. The theory is on-shell, so clearly, the constraints used for the identification of the multiplet together with the superspace Bianchi identities imply equations of motion for the component fields. We deduce these equations of motion in terms of supercova...
متن کاملsupergravity coupled to an arbitrary number of abelian vector multiplets
We present the description in central charge superspace of N = 4 supergravity with antisymmetric tensor coupled to an arbitrary number of abelian vector multiplets. All the gauge vectors of the coupled system are treated on the same footing as gauge fields corresponding to translations along additional bosonic coordinates. It is the geometry of the antisymmetric tensor which singles out which c...
متن کاملThe superspace geometry of gravitational Chern - Simons forms and their couplings to linear multiplets : a review
The superspace geometry of Chern-Simons forms is shown to be closely related to that of the 3-form multiplet. This observation allows to simplify considerably the geometric structure of supersymmetric Chern-Simons forms and their coupling to linear multiplets. The analysis is carried through in UK(1) superspace, relevant at the same time for supergravity-matter couplings and for chirally extend...
