Towards Dark Energy from String-Theory
arXiv:0801.0223 · doi:10.1142/9789812814357_0019
Abstract
We discuss vacuum energy in string and M-theory with a focus on heterotic M-theory. In the latter theory a mechanism is described for maintaining zero vacuum energy after supersymmetry breaking. Higher-order corrections can be expected to give a sufficiently small amount of vacuum energy to possibly account for dark energy.
