Dynamics of Warped Flux Compactifications
We discuss the four dimensional effective action for type IIB flux compactifications, and obtain the quadratic terms taking warp effects into account. The analysis includes both the 4-d zero modes and their KK excitations, which become light at large warping. We identify an ‘axial’ type gauge for the supergravity fluctuations, which makes the four dimensional degrees of freedom manifest. The ot...
متن کاملFour-Flux and Warped Heterotic M-Theory Compactifications
In the framework of heterotic M-theory compactified on a Calabi-Yau threefold ’times’ an interval, the relation between geometry and four-flux is derived beyond first order. Besides the case with general flux which cannot be described by a warped geometry one is naturally led to consider two special types of four-flux in detail. One choice shows how the M-theory relation between warped geometry...
متن کاملWarped Strings: Self-dual Flux and Contemporary Compactifications
String theory is a leading candidate for the quantum theory of gravitation and is the only serious unified theory of all the forces of physics. Additionally, string theory seems to be mathematically unique, and it is possible that all the parameters of physics could be determined by the dynamics of string theory. However, there are two intertwined problems. First is that string theory requires ...
متن کاملN = 3 Warped Compactifications
Orientifolds with three-form flux provide some of the simplest string examples of warped compactification. In this paper we show that some models of this type have the unusual feature of D = 4, N = 3 spacetime supersymmetry. We discuss their construction and low energy physics. Although the local form of the moduli space is fully determined by supersymmetry, to find its global form requires a c...
متن کاملWarped Compactifications and AdS / CFT ∗
In this talk we discuss two classes of examples of warped products of AdS spaces in the context of the AdS/CFT correspondence. The first class of examples appears in the construction of dual Type I' string descriptions to five dimensional supersymmetric fixed points with E N f +1 global symmetry. The background is obtained as the near horizon geometry of the D4-D8 brane system in massive Type I...
