D=4, N=2 Supergravity with Abelian electric and magnetic charges

We discuss the relation between standard N=2 supergravity with translational gauging and N=2 supergravities with scalar-tensor multiplets with massive tensors and Abelian electric charges. We point out that a symplectic covariant formulation of N=2 supergravity can be achieved just in the presence of tensor multiplets. As a consequence one can see that the formulation of the N=2 theory as it comes from IIB flux compactification, which is included in these models, is equivalent to a non perturbative phase of standard N=2 supergravity. It is also shown that the IIB tadpole cancellation condition is imposed by supersymmetry in four dimensions.Comment: 10 pages LaTex, no figure

We report on a recent investigation [1]in which F(4) supergravity [2], the gauge theory of the exceptional six-dimensional Anti-de Sitter superalgebra [3, 4], is coupled to an arbitrary number of vector multiplets whose scalar components parametrize the quaternionic manifold SO(4, n)/SO(4)×SO(n). By gauging the compact subgroup SU(2)d ⊗G, wher
