It is shown how metastable de Sitter vacua might arise from heterotic M-theory. The balancing of its two non-perturbative effects, open membrane instantons against gaugino condensation on the hiddenâ€¦ (More)

In the framework of heterotic M-theory compactified on a Calabi-Yau threefold â€™timesâ€™ an interval, the relation between geometry and four-flux is derived beyond first order. Besides the case withâ€¦ (More)

We derive inflation from M-theory on S/Z2 via the non-perturbative dynamics of N M5-branes. The open membrane instanton interactions between the M5-branes give rise to exponential potentials whichâ€¦ (More)

We consider supersymmetric compactifications of type IIB and the weakly coupled heterotic string with G resp. H-flux and gaugino condensation in a hidden sector included. We point out that properâ€¦ (More)

We show that all three conditions for the cosmological relevance of heterotic cosmic strings, the right tension, stability and a production mechanism at the end of inflation, can be met in theâ€¦ (More)

We describe the physics potential of ee linear colliders in this report. These machines are planned to operate in the first phase at a centerâ€“ofâ€“mass energy of 500 GeV, before being scaled up toâ€¦ (More)

We investigate the possibility of embedding brane anti-brane inflation into a concrete type IIB string-theory compactification with all moduli fixed. In particular, we are considering a D3-brane,â€¦ (More)

We examine heterotic M-theory with a parallel M5 brane. After deriving the four-dimensional low-energy supergravity potential including open membrane instantons, gaugino condensation and M5 braneâ€¦ (More)

Heterotic M-Theory is a promising candidate for that corner of M-theory which makes contact with the real world. However, while the theory requires one of its expansion parameters, Ç«, to beâ€¦ (More)

In cascade inflation and some other string inflation models, collisions of mobile branes with other branes or orbifold planes occur and lead to interesting cosmological signatures. The fundamentalâ€¦ (More)
