Non-Supersymmetric Stable Vacua of M-Theory

We present a non-supersymmetric compactification of M-theory down to seven dimensions which is close to a stable non-supersymmetric vacuum. This compactification is dual to a non-supersymmetric interacting conformal field theory in six dimensions. We argue that a given classical compactification of M-theory or string theory is close to a stable vacuum if it is dual to a conformal field theory w...

Classification of Supersymmetric Flux Vacua in M Theory

We present a comprehensive classification of supersymmetric vacua of M-theory compactification on seven-dimensional manifolds with general four-form fluxes. We analyze the cases where the resulting four-dimensional vacua have N = 1,2,3,4 supersymmetry and the internal space allows for SU(2), SU(3) or G2 structures. In particular, we find for N = 2 supersymmetry, that the external space-time is ...

Supersymmetric string vacua on AdS3 ×N

String backgrounds of the form AdS 3 × N that give rise to two dimensional spacetime superconformal symmetry are constructed. 1. Introduction In this letter we study the conditions on curved string backgrounds of the form AdS 3 × N that give rise to spacetime superconformal symmetry. We use the NSR formulation; for simplicity we describe the left moving sector only – it can be combined with the...

Heterotic M – Theory Vacua with Five – Branes ∗

We construct vacua of heterotic M–theory with general gauge bundles and five–branes. Some aspects of the resulting low–energy effective theories are discussed. M–theory on the orbifold S/Z2 is believed to describe the strong coupling limit of the E8 × E8 heterotic string [1] and, therefore, constitutes a particularly interesting starting point for M–theory particle phenomenology. At low energy,...
