D=4, N=2 Gauged Supergravity in the Presence of Tensor Multiplets
Abstract
Using superspace techniques we construct the general theory describing D=4, N=2 supergravity coupled to an arbitrary number of vector and scalar--tensor multiplets. The scalar manifold of the theory is the direct product of a special Kaehler and a reduction of a Quaternionic-Kaehler manifold. We perform the electric gauging of a subgroup of the isometries of such manifold as well as ``magnetic'' deformations of the theory discussing the consistency conditions arising in this process. The resulting scalar potential is the sum of a symplectic invariant part which can be recast into the standard form of the gauged N=2 theory and of a non-invariant part which yields so far unknown deformations. We also show the relation of such theories to flux compactifications of type II string theories.Keywords
