We discuss compactifications of higher dimensional supergravities which are induced by scalars. In particular, we consider vector multiplets coupled to the supergravity multiplet in the case of D = 9,8 and D = 7 minimal supergravities. These vector multiplets contain scalars, which parametrize coset spaces of the general form SO(10−D, n)/SO(10−D)×SO(n), where n is the number of vector multiplets. We discuss the compactification of the supergravity theory to D−2 dimensons, which is induced by non-trivial vacuum scalar field configurations. There are singular and non-singular solutions, which preserve half of the supersymmetries.

“…In [38] the RS spectrum of KK modes gets modified and supplemental KK and winding modes appear, because of the Σ 2 compactification. In [39] the 7D supergravity orbifold compactification on S 1 /Z 2 is considered in the context of anomaly cancellation on the boundary of the background, showing that the matter contents of the theory cannot be completely generic.…”

We discuss the cosmological implications and the holographic dual theory of the 7D RandallSundrum (RS) gravitational set-up. Adding generic matter in the bulk on the 7D gravity side, we study the cosmological evolution inferred by the non vanishing value of the brane-bulk energy exchange parameter. This analysis is achieved in detail for specific assumptions on the internal space evolution, including analytical considerations and numerical results. The dual theory is then constructed, making use of the holographic renormalization procedure. The resulting renormalized 6D CFT is anomalous and coupled to 6D gravity plus higher order corrections. The critical point analysis on the brane is performed. Finally, we sketch a comparison between the two dual descriptions. We moreover generalize the AdS/CFT dual theory to the non conformal and interacting case, relating the energy exchange parameter of the bulk gravity description to the new interactions between hidden and visible sectors.

D =7/D =6 heterotic supergravity with gauged R-symmetry

We construct a family of chiral anomaly-free supergravity theories in D = 6 starting from D = 7 supergravity with a gauged noncompact R-symmetry, employing a Hořava-Witten bulk-plus-boundary construction. The gauged noncompact R-symmetry yields a positive (de Sitter sign) D = 6 scalar field potential. Classical anomaly inflow which is needed to cancel boundary-field loop anomalies requires careful consideration of the gravitational, gauge, mixed and local supersymmetry anomalies. Coupling of boundary hypermultiplets requires care with the Sp(1) gauge connection required to obtain quaternionic Kähler target manifolds in D = 6. This class of gauged R-symmetry models may be of use as starting points for further compactifications to D = 4 that take advantage of the positive scalar potential, such as those proposed in the scenario of supersymmetry in large extra dimensions. *
