N=2 supergravity and N=2 superYang-Mills theory on general scalar manifolds: Symplectic covariance, gaugings and the momentum map

Abstract The general form of N = 2 supergravity coupled to an arbitrary number of vector multiplets and hypermultiplets, with a generic gauging of the scalar manifold isometries is given. This extends the results already available in the literature in that we use a coordinate independent and manifestly symplectic covariant formalism which allows to cover theories difficult to formulate within superspace or tensor calculus approach. We provide the complete Lagrangian and supersymmetry variations with all fermionic terms, and the form of the scalar potential for arbitrary quaternionic manifolds and special geometry, not necessarily in special coordinates. Lagrangians for rigid theories are also written in this general setting and the connection with local theories elucidated. The derivation of these results using geometrical techniques is briefly summarized.

Duality transformations in supersymmetric Yang-Mills theories coupled to supergravity

Abstract We consider duality transformations in N = 2, d = 4 Yang-Mills theory coupled to N = 2 supergravity. A symplectic and coordinate covariant framework is established, which allows one to discuss stringy “classical and quantum duality symmetries” (monodromies), incorporating T - and S -dualities. In particular, we shall be able to study theories (like N = 2 heterotic strings) which are formulated in symplectic basis where a “holomorphic prepotential” F does not exist, and yet give general expressions for all relevant physical quantities. Duality transformations and symmetries for the N = 1 matter coupled Yang-Mills supergravity system are also exhibited. The implications of duality symmetry on all N > 2 extended supergravities are briefly mentioned. We finally give the general form of the central charge and the N = 2 semiclassical spectrum of the dyonic BPS saturated states (as it comes by truncation of the N = 4 spectrum).

General matter coupled N=2, D=5 gauged supergravity.

We give the full Lagrangean and supersymmetry transformation rules for D=5 , N=2 supergravity interacting with an arbitrary number of vector, tensor and hyper-multiplets, with gauging of the R -symmetry group SU(2)R as well as a subgroup K of the isometries of the scalar manifold. Among the many possible applications, this theory provides the setting where a supersymmetric brane-world scenario could occur. We comment on the presence of AdS vacua and BPS solutions that would be relevant towards a supersymmetric smooth realization of the Randall–Sundrum “alternative to compactification”. We also add some remarks on the connection between this most general 5D fully coupled supergravity model and type IIB theory on the T11 manifold.

The Symplectic structure of N=2 supergravity and its central extension

We report on the formulation of N = 2, D = 4 supergravity coupled to nv abelian vector multiplets in presence of electric and magnetic charges. General formulae for the (moduli dependent) electric and magnetic charges for the nv + 1 gauge fields are given which reflect the symplectic structure of the underlying special geometry. Model independent sum rules obeyed by these charges are obtained. The specification to Type IIB strings compactified on Calabi-Yau manifolds, with gauge group U(1)h21+1, is given.

11-dimensional supergravity compactified on Calabi-Yau threefolds

Abstract We consider generic features of eleven dimensional supergravity compactified down to five dimensions on an arbitrary Calabi-Yau threefold. The possible relation with the heterotic string compactified on K 3 × S 1 is discussed.
