IIB solutions with N > 28 Killing spinors are maximally supersymmetric

چکیده
We show that all IIB supergravity backgrounds which admit more than 28 Killing spinors are maximally supersymmetric. In particular, we find that for all N > 28 backgrounds the supercovariant curvature vanishes, and that the quotients of maximally supersymmetric backgrounds either preserve all 32 or N < 29 supersymmetries.

The Classification of Highly Supersymmetric Supergravity Solutions
The spinorial geometry method is an effective method for constructing systematic classifications of supersymmetric supergravity solutions. Recent work on analysing highly supersymmetric solutions in type IIB supergravity using this method is reviewed [1, 2]. It is shown that all supersymmetric solutions of IIB supergravity with more than 28 Killing spinors are locally maximally supersymmetric.
متن کاملMaximally supersymmetric G-backgrounds of IIB supergravity
We classify the geometry of all supersymmetric IIB backgrounds which admit the maximal number of G-invariant Killing spinors. For compact stability subgroups G = G2, SU(3) and SU(2), the spacetime is locally isometric to a product Xn × Y10−n with n = 3, 4, 6, where Xn is a maximally supersymmetric solution of a n-dimensional supergravity theory and Y10−n is a Riemannian manifold with holonomy G...
متن کاملSystematics of IIB spinorial geometry
We reduce the classification of all supersymmetric backgrounds of IIB supergravity to the evaluation of the Killing spinor equations and their integrability conditions, which contain the field equations, on five types of spinors. This extends the work of [hep-th/0503046] to IIB supergravity. We give the expressions of the Killing spinor equations on all five types of spinors. In this way, the K...
متن کاملSchrödinger invariant solutions of type IIB with enhanced supersymmetry
We construct the Killing spinors for a class of supersymmetric solutions of type IIB supergravity that are invariant under the non-relativistic Schrödinger algebra. The solutions depend on a five-dimensional SasakiEinstein space and it has been shown that they admit two Killing spinors. Here we will show that, for generic Sasaki-Einstein space, there are special subclasses of solutions which ad...

We adapt the spinorial geometry method to investigate supergravity backgrounds with near maximal number of supersymmetries. We then apply the formalism to show that the IIB supergravity backgrounds with 31 supersymmetries preserve an additional supersymmetry and so they are maximally supersymmetric. This rules out the existence of IIB supergravity preons. It has been known for some time that a ...
