4 - D gauged supergravity analysis of Type IIB vacua on K 3 × T 2 / Z 2
نویسنده
چکیده
We analyze N = 2, 1, 0 vacua of type IIB string theory on K3 × T /Z2 in presence of three-form fluxes from a four dimensional supergravity viewpoint. The quaternionic geometry of the K3 moduli space together with the special geometry of the NS and R-R dilatons and of the T2-complex structure moduli play a crucial role in the analysis. The introduction of fluxes corresponds to a particular gauging of N = 2, D = 4 supergravity. Our results agree with a recent work of Tripathy and Trivedi. The present formulation shows the power of supergravity in the study of effective theories with broken supersymmetry.

We report on the gauged supergravity analysis of Type IIB vacua on K3 × T 2 /Z 2 orientifold in the presence of D3 − D7–branes and fluxes. We discuss supersymmetric critical points correspond to Minkowski vacua and the related fixing of moduli, finding agreement with previous analysis. An important role is played by the choice of the symplectic holomorphic sections of special geometry which ent...
متن کاملGauged Supergravity from Type IIB
We construct the complete and explicit non-linear Kaluza-Klein ansatz for deriving the bosonic sector of N = 4 SU (2) × U (1) gauged five-dimensional supergravity from the reduction of type IIB supergravity on S 5. This provides the first complete example of such an S 5 reduction that includes non-abelian gauge fields, and it allows any bosonic solution of the five-dimensional N = 4 gauged theo...
متن کاملTasi Lectures on Branes , Black Holes and Anti - De Sitter Space
In the light of the duality between physics in the bulk of anti-de Sitter space and a conformal field theory on the boundary, we review the M 2, D3 and M 5 branes and how their near-horizon geometry yields the compactification of D = 11 supergravity on S 7 , Type IIB supergravity on S 5 and D = 11 supergravity on S 4 , respectively. We discuss the " Membrane at the End of the Universe " idea an...
متن کاملAdS and dS Braneworld Kaluza - Klein Reduction
We obtain new results for consistent braneworld Kaluza-Klein reductions, showing how we can derive four-dimensional N = 2 gauged supergravity " localised on the AdS 4 brane " as an exact embedding in five-dimensional N = 4 gauged supergravity. Similarly, we obtain five-dimensional N = 2 gauged supergravity localised on an AdS 5 brane as a consistent Kaluza-Klein reduction from six-dimensional N...
متن کاملSupersymmetry of Massive D = 9 Supergravity
By applying generalized dimensional reduction on the type IIB supersymmetry variations, we derive the supersymmetry variations for the massive 9-dimensional supergravity. We use these variations and the ones for massive type IIA to derive the supersymmetry transformation of the gravitino for the proposed massive 11-dimensional supergravity. The prime example of massive supergravities must be ma...
