De Sitter Vacua from Heterotic M-Theory
It is shown how metastable de Sitter vacua can arise from heterotic M-theory. The balancing of two inherent non-perturbative effects, open membrane instantons and gaugino condensation on the hidden boundary, which act with opposing forces on the interval length, lead in particular to a stabilization of this modulus. Supersymmetry is broken spontaneously in the resulting vacua. For rather small ...
متن کاملDe Sitter Space in Supergravity and M Theory
Two ways in which de Sitter space can arise in supergravity theories are discussed. In the first, it arises as a solution of a conventional supergravity, in which case it necessarily has no Killing spinors. For example, de Sitter space can arise as a solution of N = 8 gauged supergravities in four or five dimensions. These lift to solutions of 11-dimensional supergravity or D = 10 IIB supergrav...
متن کاملConstraining de Sitter Space in String Theory.
We argue that the heterotic string does not have classical vacua corresponding to de Sitter space-times of dimension four or higher. The same conclusion applies to type II vacua in the absence of Ramond-Ramond fluxes. Our argument extends prior supergravity no-go results to regimes of high curvature. We discuss the interpretation of the heterotic result from the perspective of dual type II orie...
متن کاملAnti-de Sitter space from supersymmetric gauge theory
We construct a four dimensional Yang-Mills theory with N = 4 twisted supersymmetry whose classical vacua correspond to four dimensional anti-de Sitter space. The theory utilizes a complex gauge field whose real part is a spin connection which is used to enforce local Lorentz invariance. The imaginary part of the connection can then be interpreted as a vierbein. The topological construction ensu...
متن کاملTall tales from de Sitter space II: Field theory dualities
We consider the evolution of massive scalar fields in (asymptotically) de Sitter spacetimes of arbitrary dimension. Through the proposed dS/CFT correspondence, our analysis points to the existence of new nonlocal dualities for the Euclidean conformal field theory. A massless conformally coupled scalar field provides an example where the analysis is easily explicitly extended to ‘tall’ backgroun...
