On De Sitter Vacua in Strongly Coupled Heterotic String Theory
Abstract
Description
We describe how 4d de Sitter vacua might emerge from 11d heterotic M-theory. Non-perturbative effects and $G$-fluxes play a crucial role leading to vacua with F-term supersymmetry breaking and a positive energy density. Charged scalar matter fields are no longer massless in these vacua thus solving one of the problems of the heterotic string. Moreover, interesting dark matter candidates appear in a natural way.
