Contribution
It provides a comprehensive description of the effects of alpha'-corrections and the full Kaluza-Klein spectrum in G_2 and Spin(7) compactifications.
Findings
Inclusion of infinite alpha'-corrections in compactification models
Complete characterization of massless and massive Kaluza-Klein modes
Enhanced understanding of string and M-theory compactifications on special manifolds
Abstract
In this talk we report on recent progress in describing compactifications of string theory and M-theory on G_2 and Spin(7) manifolds. We include the infinite set of alpha'-corrections and describe the entire tower of massless and massive Kaluza-Klein modes resulting from such compactifications.
